Leader: Lan Xichen (current), Qingheng-Jun (past)
Location: Cloud Recesses | 云深不知处 note 
Region: Gusu | 姑苏 (based on modern Jiangsu)

One of the top four families in the cultivation world, the Gusu Lan Sect was founded by a monk-turned-minstrel Lan An centuries ago, and is famed for its many, many rules, the elegance of its uniform, and for producing handsome and talented disciples each generation.

Their motto is "righteousness". Direct disciples (those with actual relation to the Lan clan founder) wear a cloud-patterned forehead ribbon; whereas disciples of other families, guests and associates wear a plain white forehead ribbon.

    General Tropes 
  • Can't Hold His Liquor: According to the author, the Lans' inability to hold their liquor is genetic. This leads to Alcohol-Induced Idiocy, which starts with a specific pattern: fall asleep with one bowl, and then wake up drunk after a while, run wild, and fall asleep when the biological clock takes over to make them sleep.
  • Chekhov's Gun: The forehead ribbon. Its meaning is "to conduct oneself well", but the founder once claimed that before the person one loves, no rules are necessary, hence the forehead ribbon is a token of love between a member of the Lan clan and the lover. Wei Wuxian's reaction upon finding out was hilarious.
  • Code of Honour: All four thousand-plus rules crammed into the giant rock wall at the entrance of the Cloud Recesses.
  • Cool and Unusual Punishment: Their manner of disciplining unruly disciples? Have them copy the Lan Sect's rules at least once. After the Time Skip, Wei Wuxian realizes that the Lan Sect decided to add handstands to the punishment to ensure that the lessons stick.
  • Creature of Habit: The Lan Sect mandates waking up at five in the morning, and going to bed at nine in the evening (although night-hunts are sometimes an exception in the curfew). The trope borders on Clock King sometimes, as Lan Wangji demonstrated the ability to know what time to sleep without any indicator to tell the time, even while drunk.
  • Dress-Coded for Your Convenience: White uniforms and white forehead ribbons.
  • Everyone Knows Morse: The qin language used by the Lan clansmen, whether to communicate with the dead or to conjure a certain spell, functions in a manner similar to Real Life Morse code.
  • Everything's Better with Spinning: The donghua shows that the Lan Sect incorporates spinning in some of their attacks.
  • Fisher Kingdom: Cultivators tend to pick an area with good fengshui in order to accumulate good qi or spiritual energy. The Cloud Recesses looks like a mountain-top temple complex.
  • Heroic Neutral: Downplayed. They don't have the brutality of the Nie Sect, the despotism of the Wen Sect, or the greed of the Jin Sect, and they aren't as immersed into the cultivation world's dirty politics — which is why they rarely get into trouble. However, they rarely step up and truly uphold their clan's motto if they deem it too dangerous or troubling.
  • Hidden Elf Village: The other sects tend to be more integrated in their local communities, being the center of busy towns. The Cloud Recesses, however, is isolated at the top of a mountain behind a magical barrier.
  • Highly Conspicuous Uniform: The school colors are white. Must've been hell to clean...
  • Irony: For a clan that practices asceticism, several of its members are romantic in nature — which Wei Wuxian lampshades.
  • It Runs in the Family: Apparently, Love at First Sight and Dating Catwoman is a generational pattern.
  • Loophole Abuse: Many of their rules only count as long as one is inside the Cloud Recesses. Of course, they're still encouraged to follow the rules even when they're outside the place.
  • Lost in Translation: The meaning behind why Lan Wangji and Xichen are referred to as the Twin Jades of Lan. Jade is the stone associated with gentlemen in Chinese culture. Beautiful women are also referred to as "jade-like beauties", because their skin should be as white as white nephrite jade, as opposed to green jadeite.
  • Meaningful Surname: The Lan clan's surname comes from "伽蓝", which refers to a Buddhist temple, indicating their ancestor's origins as a Buddhist monk.
  • Not So Different: For a sect that's known for its rules of austerity and abnegation, one of the Big Bad's speeches near the finale hint that the Lan Sect had also been subtly fighting with the other sects over the war shares from the aftermath of the Sunshot Campaign. Not exactly what one should expect from a sect of ascetics, right?
    • However, the author had stated that the Lan Sect did have standards and didn't wish to participate in the First Siege. Hence, the Jin Sect intentionally triggered and exacerbated Wen Ning's loss of control to give them sufficient "cause" to join in the razing of the Burial Mounds.
  • Officer and a Gentleman: The ancient Chinese version. The Lan Sect strictly upholds "righteousness" note  as its motto.
  • One-Gender School: Averted. The Lan Sect also houses female disciples, but they're separated from the male disciples in every step of the way, from lectures and lodging, even including night-hunts. The Untamed subverts this aversion, since male and female cultivators are able to study and night-hunt together in the Cloud Recesses.
  • Razor Floss: The Chord Assassination technique, which uses qin strings (usually made of silk).
  • Theme Naming: The Lan brothers share in their birth names the water radical (氵).
    • Their titles also have an association with light; 泽 (ze) means "lustrous", while 光 (guang) means "light". As the jewels of the Lan clan, they are called the Twin Jades of Lan.
  • Veganopia: Downplayed. One of the rules of their clan states that killing livestock is forbidden. Wei Wuxian also observes that all of their meals are purely vegetarian. However, they can eat meat in meals that didn't require them killing any animal for it.
  • Warrior Monk: The Lan Sect are akin to an order of monks due to their practices in asceticism and self-discipline. However, they're still well-known for being deadly combatants and Musical Assassins.

"We only believe in what another person says based on how much we know about them. [...] You believe in your judgement, then am I not allowed to believe in my judgement?"

The current head of the Lan Sect, and known for his warm and refined, as well as his sincere and gentle nature. He is Lan Wangji's older brother; together, they are known as the Twin Jades of Lan, especially since they are very similar in appearance. He swore an oath of brotherhood with Nie Mingjue and Jin Guangyao, and he is the middle brother. Together, they are called the Venerated Triad.

  • 100% Adoration Rating: Everyone who meets him likes and respects him, even the antagonists. For all the atrocities that Jin Guangyao ever did, he never once thought about betraying Lan Xichen.
  • Accomplice by Inaction: His main crime in the novel's plot. He never intentionally does anything evil or antagonistic, but he's nevertheless almost as guilty as the novel's villains because of his naivety and his inaction, especially when either his brother or a certain friend is involved. In the times he does act, he believes that anyone can be reasoned with using words alone even when it's transparently clear that not everyone is sensible.
  • The Ace: Lan Xichen is powerful, wise and learned, but unlike his brother is also friendly and approachable. He's genuinely a nice person and he's also named the world's most beautiful .
  • Adaptational Badass: Played with. While he's stated to be an all-around skilled cultivator, but he gets a few more opportunities to show why that's the case in The Untamed.
  • Adaptational Nice Guy: He's already a Nice Guy in the novel, but the plot changes in the Live-Action Adaptation results in Lan Xichen having a considerably warmer reception to Wei Wuxian after realizing he's alive once more. He's also much calmer when he tells Wei Wuxian about Lan Wangji's whip scars and instead of blaming him for the scars and telling him he's a mistake, he says — without any hostility or anger — that he trusts Lan Wangji's decision to defend Wei Wuxian and choose him as his soulmate.
  • Ambiguous Situation: Wei Wuxian noted that in the First Siege, it was Lan Qiren and not Lan Xichen who led the Lan Sect's forces, even though Lan Xichen is the sect's leader. This small fact calls into question the extent of Lan Xichen's involvement in the event, or whether he was even involved at all.
  • Animal Motifs: Deers. Similar to cranes (which is Lan Wangji's respective animal motif), deers are seen in China as symbols of longevity and wealth and are admired for their graceful nature — which fits both Lan Xichen and his sect.
  • Armor-Piercing Slap: He gives one to Jin Guangyao in the final episodes of The Untamed after being so outraged with the latter's actions and his lack of remorse about them.
  • At Least I Admit It: When he's called out for his Selective Obliviousness towards Jin Guangyao, while Lan Xichen explains why he's defensive of the man, he doesn't outright deny it.
  • Audience Surrogate: He's essentially speaking on the reader's behalf when he remarks how Wei Wuxian chose the worst time and situation to confess his love to Lan Wangji.
  • Awful Truth: He tells Lan Wangji that he doesn't want to easily accept that his long-time friend is a liar and a murderer because accepting it and all the implications that come with it would be too much for him to take. True enough, when that time eventually came, the full impact of the revelation shatters his spirit (metaphorically speaking) and drives him into seclusion.
  • Beware the Nice Ones: Lan Xichen is one of the most genial characters in the story, but his patience still has its limits.
    • He opts to play peacemaker more often than he should, but Lan Xichen is still a powerful cultivator. If needed be, he won't hesitate to raise his blade when he knows it's his only remaining option. His dearest friend learns this the hard way.
    • No matter what situation Wei Wuxian gets involved in with Lan Wangji, Lan Xichen always treats the former civilly. Which is why it's jarring to see him show outright anger at Wei Wuxian when he tells him of the events at the Nightless City and what Lan Wangji had done for him and went through for him then, even telling him point-blank that he's the only mistake his younger brother has ever made.
  • Big Brother Instinct: He's a good brother to Lan Wangji, and to his sworn brother Jin Guangyao. In fact, his mistaken assumption that Wei Wuxian was toying with his brother's feelings was one of the few things that angered him; and his platonic affections for Jin Guangyao are what makes him unwilling to believe the horrible truth about his friend.
    • He also has a soft spot for Nie Huaisang as he looks after him once he becomes sect leader and tries to help him with any of his problems. In the audio drama Wei Wuxian remarks that Lan Xichen's spoiled Nie Huaisang to the point that he's become useless. His protectiveness over Nie Huaisang could be due to the fact he was sworn brothers with Nie Mingjue, so he feels obligated to look after his friends little brother.
  • Break the Cutie:
    • The first time was when the Cloud Recesses was razed to the ground in the lead-up to the Sunshot Campaign against the Wen Sect, and he was forced to flee for his life with the contents of the Lan Sect's library.
    • He went into seclusion after the death of Jin Guangyao.
  • Broken Ace: He's highly regarded as the best cultivator of his generation, as well as a shining example of what a Lan clansman should live up to. By the epilogue, he's a grieving recluse, with only his younger brother visiting him periodically. During the Banquet extra, Wei Wuxian observed that Lan Xichen seems to be neglecting his health and has become somewhat absent-minded.
  • Broken Pedestal: By the time of the final arc, Lan Xichen can no longer deny the truth about Jin Guangyao and consequently loses any faith he had left for his friend, and it gets worse from there to the extent that he himself is left broken and in doubt of himself and everyone else.
  • Bystander Syndrome:
    • In the events following the Sunshot Campaign, he doesn't do almost anything, let alone help his brother with Wei Wuxian. While he, in his defense, had little to no idea of the truth of the situation to act accordingly; it must be noted that he still sided with everyone else in crusading against the Yiling Patriarch. He even argued with Lan Wangji that Wei Wuxian was already a lost cause.
    • He's also guilty of being a fence-sitter when it comes to matters involving Jin Guangyao, partly because he doesn't want to accept that the friend who always helped him in his time of need was in truth a manipulative and duplicitous man who committed countless crimes.
  • Character Tics: In The Untamed, Lan Xichen has a tendency to close his eyes and sigh or take a deep breath whenever he's faced with a stressful situation.
  • Conflicting Loyalties:
    • In the novel's plot, part of the conflict Lan Xichen is faced with is whether he should side with his biological brother against his sworn brother or the other way around. What doesn't help is that he's close to both of them. While he would never go against Lan Wangji, he's also reluctant to confront Jin Guangyao since it would mean admitting that his closest friend is an evildoer.
    • Even before the current events of the novel, Lan Xichen was faced with the friction between two of his sworn brothers and handled it badly. His attempts to make peace only resulted in him being played into Jin Guangyao's hands by preventing Nie Mingjue from acting more decisively, and Jin Guangyao used the songs Lan Xichen taught him to help kill Nie Mingjue.
  • Cool Big Bro: Lan Xichen is a good brother to Lan Wangji, being patient and respectful and equally doting and loving. In return, Lan Wangji respects and trusts him and even confides to him about his troubles sometimes.
  • Despair Event Horizon: After Jin Guangyao's death, Lan Xichen completely shuts himself off from the world. Even though Lan Wangji visits him often, even he's not certain how long it will take for his brother to start recovering.
  • Does Not Know His Own Strength: Subverted, at least most of the time. Nearly-supernatural arm strength is a common trait shared by the Lan clansmen. Like his brother, Lan Xichen seems to have a control over this, but the audio drama shows that he doesn't know how to apply the right amount of strength whenever he would wash his clothes, causing him to accidentally tear them.
  • Dramatic Irony:
    • Lan Xichen never believed any suspicions directed towards Jin Guangyao, even when his own brother is harboring said suspicions, as he's certain that he knows who Jin Guangyao is. Except that no, he really doesn't.
    • In the past, he was the one who was certain and clear-minded whereas his younger brother was facing internal conflict. In the final arc, their positions are reversed, with Lan Xichen falling into self-doubt and Lan Wangji being sure of his thoughts and actions. Additionally, Lan Wangji is reunited and bound to his (romantically) loved one, while Lan Xichen is pained with the betrayal and loss of his (platonically) loved one.
    • As Lan Wangji himself notes in one of the extras, in the past his brother would visit him and talk to him while he was in seclusion; but now, the situation is completely reversed.
    • Despite nearly losing his home to the tyranny of the Wen Sect, when the Jin Sect started to show that they're sharing the Wen Sect's ambitions of ruling over all the cultivation clans, Lan Xichen chose not to oppose them even when Wei Wuxian explicitly pointed out that Jin Guangshan's actions mirrored Wen Ruohans, with Lan Wanghi not disagreeing with Wei Wuxian's accusation.
  • Easily Forgiven: Possibly. All of the Four Great Sects were present during the First Siege, and while Wei Wuxian noted that it was Lan Qiren and not Lan Xichen that led the Lan Sect, there's still the possibility that Lan Xichen was still present during either Wei Wuxian's death, the massacre of the Wen survivors, or both. Even if that is actually the case, he and Lan Wangji remain close, and Wei Wuxian doesn't appear to hold anything against the man. Granted, thirteen years have passed since then, so it's possible the forgiveness happened off-screen.
  • Fatal Flaw: Lan Xichen is a trusting person who tries to see the best in everyone, but in the harsh world of politics this trait can cause more harm than good. His centrist outlook causes him to be complacent with many things even if they go against his moral fiber, because of his reluctance to speak on behalf of only one side. It's also practically a fact that he has a bias towards Jin Guangyao and is hesitant to entertain anyone's suspicions of him even when the signs are right there, which allows Jin Guangyao to get away with most of his misdeeds. When he does finally share their suspicions once presented with more-than-concrete proof, by then it's already too late to do anything about it. As such, his choice to go into seclusion in the ending reflects his difficulty in reconciling with his faults and his guilt and doubts about his misplaced trust.
  • Foil:
    • To Xiao Xingchen.
      • Both are gentlemanly people who are loved by many, and are Unwitting Pawns in the villains' plans, with said villains taking advantage of their kindness and/or handicaps to get away with their actions.
      • However, Lan Xichen was reluctant to believe Wei Wuxian and Lan Wangji's claims about Jin Guangyao until he couldn't deny it any longer; but even then he still has his doubts. On the other hand, Xiao Xingchen had absolutely no idea that the man he saved and who lived with him for years was the criminal he apprehended years ago, and when he learns the truth from A-Qing, he believes it. And yet while both feel enraged and/or betrayed by the truth, they still demand answers, which leads them one step closer to their undoing.
      • When the Awful Truth about their companion completely sinks in for both men, they cross the Despair Event Horizon. Xiao Xingchen commits suicide, and Lan Xichen falls into depression.
    • To Nie Huaisang. To the rest of the cultivation world, Lan Xichen comes off as an extremely wise and learned man with the best judgment whereas Nie Huaisang is the no-gooder who knows nothing as he always exclaims and can't do anything right on his own. However, how society sees them contrasts the kind of people they really are.
      • Lan Xichen may seem like someone who can provide a good solution to a complication as soon as it's presented, but in truth he is passive and has a near-extreme inclination to neutrality even in situations where it's blatantly obvious that lending his opinion or putting his foot down would end the conflict much sooner, because he often fails to realize that peace is not tantamount to raising one's voice over just causes even if it invites scrutiny. While he is intelligent, it doesn't mean he lacks naivety, and said naivety causes him to be blind to the damning problems around him and commit severe mistakes born out of misguided judgement.
      • On the outside, Nie Huaisang is a weak-willed ignoramus who is only an Authority in Name Only who constantly whines about not being involved in anything. However, he doesn't explicitly takes sides because he knows his role as a Wild Card, and is far more than he lets on when it comes to what the cultivation world both hides and shows, but he lets other people think otherwise because he prefers it that way. He also doesn't get involved in the affairs of others purely because he chooses his battles and is able to assess whether he should act in a situation or simply watch from the sidelines.
  • Foolish Sibling, Responsible Sibling: Both he and Lan Wangji are, by default, responsible, and he trusts his younger brother to lead their sect when he isn't around. Once Jin Guangyao is involved, however, one becomes the Foolish Sibling while the other becomes the Responsible Sibling; since the aforementioned matter brings in the issue of partiality. Guess who's guilty of that.
  • Forgetful Jones: He gets a bit absent-minded when he's drunk, such as when he frantically looked for his xiao despite holding it the entire time. He then becomes generally inattentive after Jin Guangyao's death, since during the Banquet extra, he's so spaced out that he reads some documents wrong.
  • Four-Temperament Ensemble: Phlegmatic.
  • Freudian Excuse: It's heavily implied that his parents' history — which also details how his father was torn between defending his love and his clan — influenced Lan Xichen's aversion of starting any conflict or picking a side, even if it's for a right cause.
  • Friend to All Living Things: The extras in both the novel and the audio drama show that Lan Xichen has a soft spot for rabbits. The audio drama also reveals that he's the reason why there's a currently whole warren of them residing in the Cloud Recesses (aside from the ones Wei Wuxian gifted to Lan Wangji).
  • Genki Boy: He becomes over-enthusiastic when drunk, and his every sentence would end with three exclamation marks.
  • Good Is Dumb: Played with. He's not what anyone would call stupid, but he's naive, and tragically so. If the author's postscripts are anything to go by, just because Lan Xichen is the top-ranked cultivator doesn't automatically mean he's the most intelligent of the lot. He's incredibly book-smart and is a great battle tactician, but he's far from shrewd (politically or otherwise) and lacks street smarts.
    Mo Xiang Tong Xiu: I have no idea why some readers think he's someone who "hides his wit deep inside". In truth... I've never shown any traits of his that could be interpreted this way. To be able to see through his brother's little thoughts doesn't mean it's the same with others, and to become sect leader didn't require deep thoughts and acute perception. Perhaps it was only because he had a high birth, nice personality and excellent performance...
  • Good Is Not Nice: Inverted and downplayed. Lan Xichen is a Nice Guy in every sense of the word, and he earnestly tries to do good. However, his centrism causes him to fall short of being genuinely good, as when he's faced to do something that is morally right yet risks conflict or something that is morally wrong but doesn't incite any public or political trouble, he tends to choose the latter.
  • Good Is Not Soft: Despite his reputation for his kindness, Lan Xichen — as a cultivator and one of the leaders in the Sunshot Campaign — has spilled blood before.
  • Head-in-the-Sand Management: Not usually. However, the protagonists realize that it's hard for them to get through to Lan Xichen whenever they discuss about Jin Guangyao and his true character. Lan Xichen's decision to seclude himself after his friend's death could be even seen as an act of both grief and denial.
  • Horrible Judge of Character: Technically this, due to his unrelenting belief in Jin Guangyao right before being captured and held hostage. To be fair, many other men, including Nie Mingjue who knew Jin Guangyao's tendency to kill the people who insulted him, have also been fooled by Jin Guangyao.
  • Hypocrite: In the Guanyin Temple arc, he warns Jiang Cheng to not listen to anything Jin Guangyao says since the guy is silver-tongued and can turn someone's words against them. Minutes later, he ignores his own advice, which both his brother and Wei Wuxian call him out on. He persists anyway, and while it doesn't get him killed, it still backfires on him badly.
  • Ironic Echo: Everything he says about how his trust in Jin Guangyao mirrors Lan Wangji's own belief in Wei Wuxian blows up in his face in the finale.
  • Jerkass Has a Point: As harsh was it was to call Wei Wuxian a mistake his younger brother had made, Lan Xichen had good reason to be angry at him for (albeit unknowingly) hurting Lan Wangji's feelings by being oblivious to them and consequently (albeit unknowingly) leading the latter on. In Wei Wuxian's defense, he had his own understandable reasons for not picking up on Lan Wangji's affections sooner, but Lan Xichen's entire speech nevertheless allowed him to finally get his thoughts straight and properly confess his love to Lan Wangji.
  • The Kirk: A deconstruction of this trope. Lan Xichen tries to play peacemaker between his friends, mediating conflict between two people who have completely different personalities. However, due to his trusting nature, he ends up being used by more unscrupulous people to help them weasel out of punishment and reprisal from other parties that have valid reasons to be angry.
  • Lantern Jaw of Justice: He has a sharp and squared jawline in The Untamed.
  • Like Father, Like Son: Lan Xichen secluded himself as he was broken by how his most trusted friend was in reality a murderous Manipulative Bastard; similar to how his father went into seclusion out of guilt for defending his wife, who had also killed his mentor.
  • Magic Music: Like the rest of his clan, Lan Xichen also practises musical spells. But compared to the other Lan Sect members who typically use the guqin, Lan Xichen uses a xiao instead.
  • Meaningful Name: Liebing, the name of his xiao, translates to "cracked ice" — which mirrors his emotional and mental state in the finale.
  • Morality Pet: He's the only person Jin Guangyao is genuinely kind to.
  • Moral Myopia: He's not as tunnel-visioned as some other characters, but Lan Xichen's passivity causes him to have a shaky grasp on what's right and wrong.
  • My God, What Have I Done?: The realization that he had misjudged Wei Wuxian the entire time and that he never really knew Jin Guangyao's true character and that he unknowingly enabled some of his friend's wrongdoings due to personal bias born from gratitude hits Lan Xichen so hard that he's overcome with despair and starts to live in seclusion.
  • Never Gets Drunk: The Lan Sect's inability to hold their liquor is kept in The Untamed, but Lan Xichen finds a way around this by using his golden core to dispel the alcohol's effects in situations where he's required or forced to drink.
  • Nice Guy: His defining mark. Lan Xichen is constantly nice to everyone regardless of their social status.
  • Non-Action Guy: In the present, he doesn't fight that much. In the past, though, he was one of the three to help in killing Wen Ruohan besides Nie Mingjue and Jin Guangyao.
  • Not So Above It All: He's not a stick in the mud, but the jovial and larger-than-life personality he exhibits while drunk hints that like his younger brother, he too wishes to let loose and have fun once in a while without worrying about his sect's rules.
  • Not So Different:
    • Lan Xichen didn't do much to help the Jiang Sect even when it became crystal clear to him that the rest of the clans are trying to sow seeds of distrust in Wei Wuxian and Jiang Cheng's relationship, with some of his dialogue implying that he's well aware of the truth about how the Jin Sect's acting but he chooses to outright ignore it. And as the Big Bad would state in the finale, the Lan Sect also secretly shared the Jin Sect's sentiments of not wanting to see the Jiang Sect rise in power as quickly as it was. This hints that Lan Xichen, while far from immoral or amoral, is not immune to acting out of self-interest over justice.
    • Like his brother, Lan Xichen's devotion to a loved one causes him to suffer in grief after said loved one's death. It doesn't help that he learned that the same person turned out to be the real villain.
    • In his final moments, Jin Guangyao accuses Lan Xichen of being as intolerant of him as Nie Mingjue was. However, this is an erroneous statement since until near the end, Lan Xichen always made an effort to defend Jin Guangyao, only to understandably lose all trust in him once everything about his misdeeds came to light.
  • Oblivious to His Own Description: Lan Xichen stated that his brother's worst mistake was falling in love with Wei Wuxian, except that he's actually the one deserving of the same criticism since he trusted and sided with the wrong guy. And unlike Lan Wangji, who sees both the good and bad in Wei Wuxian, Lan Xichen tries to keep seeing only the good in Jin Guangyao.
  • Pacifism Backfire: This sums up majority of the conflict he's both causing and facing. Because of his reluctance to take sides, take more extreme but necessary actions, or believe any damning information about the people he's personally close to, blood inevitably ended up being shed. Even then, he continues to believe that everything can be handled without any death; and when it finally hits him that nothing is that simple, he has a hard time taking it well.
  • Plain Palate: The chibi donghua spin-off shows that like his younger brother, Lan Xichen is unable to handle spicy food.
  • Please Spare Him, My Liege!: The audio drama reveals that he begged Lan Qiren to not punish Lan Wangji with the discipline whip in spite of his brother's grievous crime of attacking the clan elders.
  • Power Trio: With Nie Mingjue and Jin Guangyao.
  • Reality Ensues: Lan Xichen is a prime example of how while it is normally wise to take time and weigh your options, in some situations, it's not automatically the correct course of action because some outcomes will not wait for his judgment.
  • Reasonable Authority Figure:
    • Lan Xichen is more lenient than Lan Qiren with Wei Wuxian being a prankster (even with his younger brother often on the receiving end of those pranks), as he understands that Wei Wuxian means no harm and is just being the free-spirited youth that he is.
    • In general, he's patient and diplomatic to everyone, which is what earned him his 100% Adoration Rating. Even when he has partialities about certain issues, he'll still try to keep an open ear and mind. However, he's also a deconstruction of the trope since while he's congenial towards anyone he meets, it doesn't mean he always knows what to do nor does he always take the proper course of action in dire situations.
  • Red Herring: There are a few scenes in the novel that seem to hint at him being on Jin Guangyao's side the whole time and is merely feigning innocence. It doesn't help that he's the first figure of import that Wei Wuxian sees in the Guanyin Temple, and none of the monks and the Jin cultivators stationed there are treating him like a prisoner or an intruder. Except that no, he's actually being held hostage there, and he's only one of Jin Guangyao's Unwitting Pawns.
  • Selective Obliviousness: Some of his dialogue hints that deep down he had long suspected that Jin Guangyao may not be who he seems to be, but he always ignored his own — and everyone else's — misgivings since he didn't want to accuse his friend. In his defense, Jin Guangyao has been doing a splendid job fooling him and everyone else, which just helps fuel Lan Xichen's disbelief.
  • Shipper on Deck: Played with. Lan Xichen encouraged Lan Wangji to befriend Wei Wuxian, not to fall in love with him; although even when he holds Wei Wuxian at fault for his younger brother's actions during the siege at the Nightless City, Lan Xichen still called out Wei Wuxian on not knowing about Lan Wangji's feelings for him sooner, and he doesn't object when the two confess to each other and become a couple.
  • Shut Up, Hannibal!: When Jin Guangyao attempts to talk himself out of being apprehended by explaining the motives and reasons behind many of his crimes, Lan Xichen fires back by stating that he's only in the situation he currently is in because of said crimes.
  • Sibling Yin-Yang: Unlike his younger brother, Lan Xichen is more sociable and approachable.
  • Strong Family Resemblance: He and Lan Wangji are brothers so this is a given, but one would be forgiven for thinking that they're twins at times.
  • Thousand-Yard Stare: In The Untamed, he has an empty and distant look on his eyes after Jin Guangyao dies.
  • Turn Out Like His Father: From leading the Lan Sect, to being involved with a loved one who has a murky past, to not being able to live with guilt, all the way to imposing himself in near-total solitude.
  • Unwitting Instigator of Doom: While he meant well, one can only wonder the many things that could have ended differently had Lan Xichen never suggested that Nie Mingjue take up an oath of brotherhood with him and Jin Guangyao, which made it easier for the latter to manipulate and poison the former.
  • Unwitting Pawn: While Jin Guangyao never harmed Lan Xichen and truly cared for him, he still used their friendship and treated him as a tool. In particular, he used the songs and knowledge Lan Xichen taught him to kill and attempt to kill his enemies.
  • What Does She See in Him?: One of the gatcha extras of the audio drama reveal that even long before snapping at Wei Wuxian for not being aware of Lan Wangji's feelings for him, Lan Xichen already believed that Wei Wuxian isn't worthy of Lan Wangji's love via his comment of how it would be a shame if "Mo Xuanyu" — Lan Wangji's newest companion — ended up being similar to Wei Wuxian. As it turns out, the egg is on his face...
  • World's Most Beautiful Woman: Gender-inverted; he's at the top of the list of cultivator gentlemen in his generation, which implies that on some level his looks surpass Lan Wangji's. The novel does state that both are considered equally good-looking, but Lan Xichen has more charm due to being more sociable.

"If one becomes complacent and proud just because they defeated a few simple mountain beings in their home and hold some empty reputations, one would definitely bring disgrace upon themselves, sooner or later."

The elder of the Lan family and uncle to the Twin Jades of Lan. He is stern, pedantic, and a strict teacher who turns out outstanding students. The former two traits make people avoid him, but the last trait makes parents try everything to get their kids into the Cloud Recesses for a period of study. The only stain on his otherwise pristine record is Wei Wuxian.

  • Adaptational Jerkass: His choice to subject Lan Wangji to thirty-three lashes for injuring thirty-three clan elders might be seen as too much. However, it's much more reasonable compared to how he reacts in the live-action, where he has Lan Wangji whipped three-hundred times not for attacking his own clan, but for merely defending Wei Wuxian's lair in the Burial Mounds from the Jin Sect. Apparently, standing up to the most powerful cultivation clan is a much more severe offence than attacking your own clan, whether or not it's for the same purpose.
  • Adaptational Nice Guy:
    • The few extra scenes he gets in the donghua gives more facets to his character than just being the archetypal pedantic, strict, and uncompromising mentor and uncle figure. Some scenes are also tweaked to make him less harsh towards Wei Wuxian.
    • Both the novel and the audio drama stated that he scolded Lan Wangji for repeatedly visiting his mother's house even long after she's dead. But in The Untamed, a flashback centered around the same scene features Lan Qiren approaching his nephew and giving him a sympathetic pat on the shoulder instead.
  • Adaptation Expansion: He has a bit more screentime in the donghua, particularly in the Sunshot Campaign arc — where he expresses worries that the Wen Sect will become trouble soon and is one of the first to advocate for fighting back against the Wen Sect when they start making their move.
  • Beautiful All Along: He doesn't look unattractive per se, but according to the author he looks a lot more handsome without the beard. Fans who know their way around editing images completely agree.
  • Berserk Button:
    • Any signs of divergence from his standards of either cultivation practice or etiquette. A certain son of Cangse Sanren is the walking embodiment of aberration in his eyes, hence why Lan Qiren is always about to suffer a heart attack whenever he sees him. It only gets worse for him after Wei Wuxian marries his younger nephew.
    • Don't think of doing anything to his beard. It's why he even hates a certain mother-son duo in the first place.
  • Blood from the Mouth: There are instances when he coughs blood due to extreme stress.
  • Butt-Monkey: He had his hands full when he was teaching Wei Wuxian, who caused him no end of grief.
  • Character Tic:
    • The man sure loves to stroke his beard.
    • He tends to break into a coughing fit when he gets stressed enough.
  • Disappointed in You: He says this to Lan Wangji while having him flagellated for acting in Wei Wuxian's defense.
  • Dramatic Irony: Lan Qiren didn't want both of his nephews to make the same mistake his older brother did, but he feared that Lan Wangji was much more susceptible to suffering his father's fate due to his association with Wei Wuxian. It turns out, however, that Lan Qiren was worrying about the wrong nephew. It's actually Lan Xichen who would end up like his father, becoming a recluse after losing his closest friend, who also betrayed his trust.
  • Easily Forgiven: Wei Wuxian noted that it was Lan Qiren — not Lan Xichen, the sect leader — who led the Lan Sect during the First Siege. He then does the same again during the attempted Second Siege. However, Lan Wangji holds no contempt for his uncle for either instances. In the first case, thirteen years did pass so possibly the forgiveness did take time, but either way the reader isn't shown the circumstances behind it. In the latter case, the lack of resentment likely has to do with the fact that the siege ended in failure.
  • Education Mama: Education Uncle, but you get the point. He took care of both his nephews since they were born, and was nothing short of strict on them to ensure that they grew up well-taught and well-mannered and wouldn't end up like their father. However, he's also expecting them to always be the ideal Lan Sect disciple, which places a strain on their well-being before they're even aware of it.
  • Foil: To Yu Ziyuan.
    • Both have a temper, especially where Wei Wuxian is involved. Between the two, however, Lan Qiren is the less volatile one, and he's willing to listen to Wei Wuxian if the latter is speaking with sense. And in spite of his dislike for him, he's willing to tolerate Wei Wuxian, even if only for his nephew's sake. Yu Ziyuan, on the other hand, made sure to make Wei Wuxian feel miserable every time the two of them are in the same room by bringing up how he's of a lesser rank than them, and she would always find fault in him in every situation.
    • They're both strict towards their charges and expects nothing but the best from them, which leads to said charges having issues in some way. As a result, the Lan brothers are left sheltered and lacking in proper interpersonal skills or relationships.
      • However, Lan Qiren acted with his best intentions and never mistreated them in any way. At worst, he's Innocently Insensitive to the conflicts they're left with, both then and now, partly because of his insufficient knowledge in emotional care and partly because of pride, his strict adherence to the rules, and/or his misconceptions about how a perfect disciple should be.
      • On the other hand, Yu Ziyuan verbally beat down her son if he fell even slightly short of her standards, and would always compare him to Wei Wuxian and then mock them both. She also heavily contributed to the myriad of flaws that Jiang Cheng currently has, and said flaws are what caused many things to go wrong in both his emotional growth and his friendship with Wei Wuxian.
  • Foolish Sibling, Responsible Sibling: He serves as the Responsible to his older brother's Foolish Sibling. After Qingheng-Jun went into seclusion, which caused him to neglect his duties as both a sect leader and father, Lan Qiren took over his brother's duties.
  • Grumpy Old Man: This is Lan Qiren in a nutshell.
  • Honor Before Reason: He's usually this, but he averts the trope in life-or-death matters where he knows acting on his personal hang-ups and prejudices would only worsen the situation.
  • Hypocrite: While he's not the worst one around among the cast, Lan Qiren can still be self-contradicting in some ways.
    • He's vocal about upholding his clan's motto of "righteousness", but he only sticks his neck out when a common enemy is involved, and will not do anything that would put him or his sect in danger, even if that "anything" is doing what's right. While this may be less out of bias or convenience and more out of worry for his clansmen, it's still something one wouldn't expect from someone who preaches about the righteousness of his clan and its rules.
    • Likewise, Lan Qiren is strict on himself and on others about following the rules of his clan... so as long as it works in their favor. For example, as far as the majority of the Lan Sect knew, Madam Lan never left her house because she suffered an illness, which isn't the case. However, Lan Qiren didn't do anything to clarify the matter even though their sect forbids dishonesty, since the truth was much more politically scandalous.
  • Irrational Hatred: Downplayed. While he will listen to Wei Wuxian if he is raising a fair point, it doesn't change his extremely negative opinion of the the younger man, even long after his name got cleared. Said negative opinion is formed from Wei Wuxian's incorrigibility and his own belief that Wei Wuxian is a bad influence on Lan Wangji, even when the plot has shown multiple times that he's the exact opposite of a bad influence.
  • Jerkass Has a Point: When Wei Wuxian suggested that using resentful energy is no different from using spiritual energy, Lan Qiren rebutted that he can't be sure that he could completely control resentful energy and ensure that it wouldn't backfire on him. Given what happened to Wei Wuxian before his death and the vague details about said death, his words counted as ominous foreshadowing.
  • Karma Houdini: No matter how little the role he played in the First Siege, he still participated in said siege, but like everyone else he doesn't get any legal punishment for it. And even with some truths coming to light, Lan Qiren continues to hold a negative view on Wei Wuxian, yet he doesn't get so much as a calling out for it. Granted, he does have to live with the fact that his nephew and Wei Wuxian are now married and he'd have to tolerate Wei Wuxian's now-constant presence in the Cloud Recesses — both of which are likely to make him live with a headache every minute of every hour of every day, so there's that.
  • Love Is a Weakness: Downplayed in that Lan Qiren doesn't have a problem with familial love but with romantic love instead. Part of the reason Lan Qiren is strict on his nephews is because of what happened with his brother, who fell into ruin because of his feelings for Madam Lan.
  • Never My Fault: Lan Qiren believes that as someone who always sticks to the rulebook, he could never do or say anything wrong. Mo Xiang Tong Xiu confirmed him to have had this behavior since years ago, when said attitude had nearly cost Jiang Fengmian and Wei Changze's lives but he refused to admit to his faults. Even his anger over Cangse Sanren shaving his beard as revenge for endangering her friends just shows that he failed to see the error of his ways. That, or he was just too proud of his goatee.
  • Never Say "Die": When Lan Wangji was still young, Lan Qiren never told him outright that his mother was dead and that she was just "gone", which his nephew didn't understand.
  • Noodle Incident: The author revealed that he also taught Wei Wuxian's mother, who once cut his beard as part of a prank. History Repeats when Wei Wuxian himself did the same thing.
    • An interview with the author eventually revealed why Cangse Sanren committed the prank. During a night-hunt, Lan Qiren almost got Jiang Fengmian and Wei Changze killed but refused to apologize for it, so Cangse Sanren retaliated on their behalf by cutting off his beard.
  • Obnoxious In-Laws: He already had a huge dislike of Wei Wuxian when he was a student at the Cloud Recesses, and after Wei Wuxian marries Lan Wangji, Lan Qiren's dislike grew even more as he immediately added new rules to the wall that forbids the juniors from talking to Wei Wuxian.
  • Old Soldier: He's the one who taught swordplay to both his nephews, which means that he himself is a more than capable fighter.
  • Parental Marriage Veto: Attempted. Lan Qiren didn't approve of Wei Wuxian as a student, and he doesn't approve of him as Lan Wangji's cultivation partner either. While he reluctantly acknowledges their marriage, he still shows his disapproval by creating the rule where no one is to talk to Wei Wuxian; although this is a futile effort.
  • Parents as People: Lan Qiren is the type of person who does what he thinks his best for his charges but fails to realize what might actually be best for them. Unlike most of the other parental figures in the novel, he's never emotionally abusive or neglectful and means completely well with his strict upbringing. However, the expectations he places on his nephews leaves them repressed and unable to let loose once in a while, which negatively affects them in the long run. Lan Wangji gets better from this issue thanks to Wei Wuxian's influence, but Lan Xichen doesn't as he was never prepared for the possibility of experiencing severe mental trauma. Lan Qiren isn't unsympathetic to their predicaments, yet he tends to worry more about how his nephews are no longer the "perfect children" in his eyes.
  • Perpetual Frowner: He's certainly not a mellow and happy guy.
  • Pet the Dog: He's inflexible and close-minded, but he's not heartless.
    • Only in the donghua. While Wei Wuxian's antics drive him up the wall, he approved of Lan Wangji's decision to find and shelter Wei Wuxian and the Jiang children after the Wen Sect's attack on Lotus Pier, showing at least some level of concern for the young man.
    • He's far less fond of Wei Wuxian at present, and it doesn't change after the younger man's marriage to Lan Wangji. But while it took a lot of convincing on his nephew's part, Lan Qiren eventually acknowledges him as part of the Lan family (even if reluctantly) by inviting him to their family banquet.
    • He led the Lan Sect's forces in the First Siege, although whether he actually killed anyone in the Burial Mounds is unknown. However, in spite of his initial anger, he let Lan Wangji officially adopt Wen Yuan into the Lan clan.
  • Pride:
    • He fits the character archetype of the grouchy old man who's stuck in the teachings he grew up with and doesn't consider new or improved ideas. He's also not someone who's willing to admit that he's wrong and there are some things he should improve upon or adjust to.
    • He feels proud of his nephews, given how they're regarded by almost everyone else as the "embodiment" of perfection. Unfortunately, raising them to be ideal and perfect causes them to restrict almost every honest thought and emotion they have to uphold their flawless reputations; yet he never becomes aware of this.
  • Principles Zealot: Crosses over with Black-and-White Morality. Aside from his stringency about his sect's rules, he strongly advocates for doing the right thing. However, the moment someone breaks the rules to do that, he immediately sees them as a traitor.
  • Promotion to Parent: Given how the mother is technically locked up and the father is in secluded cultivation, Lan Qiren essentially raised Xichen and Wangji.
  • Properly Paranoid: In the donghua, he was suspicious of the Wen Sect's intentions and feared war between the sects breaking out. His fears are later proved true.
  • Reasonable Authority Figure: At least most of the time. He may be grouchy and has very rigid viewpoints, but in times of duress he is fair in his judgment, even when in the same room with the people who get on his nerves the most.
  • Sadist Teacher: Not sadistic per se. But while he's strict, Lan Qiren isn't always what one would call a fair and impartial teacher. For example:
    • When he asked Wei Wuxian a few questions about cultivation, the latter answered each one correctly. However, Lan Qiren dismisses them by saying that such facts are common knowledge and that no one should feel proud for getting those questions right. Then when Wei Wuxian doesn't answer his next question, he has his nephew answer and takes the opportunity to put Wei Wuxian on the spot. Even the young man is aware of what Lan Qiren was doing.
    • When Wei Wuxian gets caught passing cheat sheets to his classmates, Lan Qiren subjects only Wei Wuxian to detention and doesn't give the same level of punishment to the other students who attempted to cheat through his exams.
  • Skewed Priorities: When it comes to his nephews, while he genuinely loves them, he's also borderline obsessed with making sure that they continue to meet his standards for an upstanding disciple. This tends to take precedence over more pressing matters, making him oblivious at best and indifferent at worst to his nephews' personal struggles.
    He felt that of these two of his proudest disciples who had been absolutely perfect, neither listened to him anymore and both gave him much worry.
  • Stern Teacher: He's both famous and infamous for this.
  • Strict Parents Make Sneaky Kids: Lan Qiren increased his nephews' education in order to ensure that they wouldn't make the same mistakes their father made. However, History Repeats Itself with Lan Wangji eloping with Wei Wuxian, and Lan Xichen going into seclusion after the death of his beloved friend.
  • Throw the Book at Them: His reaction whenever a student provokes his anger. Most of the time the student in question just so happens to be Wei Wuxian.
  • Younger Than He Looks: While his exact age is unspecified, is far from the range expected from grandfathers; he's the younger brother of Qingheng-Jun, even. However, his personality and his facial hair adds several more years to how old he appears to others.

"It is as though if either Senior Mo or Hanguang-Jun are present, I will not need to be scared or worry about anything."

Lan Sizhui is one of the younger-generation cultivators that Wei Wuxian first meets after he came Back from the Dead. The Nice Guy, he immediately inspires good feelings in Wei Wuxian, who thinks that Lan Sizhui is just the latest of the Lan clan's famously strict education.

  • Adaptation Expansion: In the novel, he wasn't present in the events of the Guanyin Temple arc except for the aftermath; whereas he gets involved halfway in the live-action drama. The first of the two sequel movies also focuses on him and Wen Ning going a night-hunt which takes place after the events of the series finale.
  • Affectionate Nickname: In the past he was called A-Yuan by the other Wen's and Wei Wuxian. When meeting with Wen Ning who realizes who he is, he asks if he could call him A-Yuan which Lan Sizhui allows.
  • Amnesiac Hero: He spends most of the book until after the climax forgetting about his past as part of the Wen family. Granted, a high fever at two or three years old would have encouraged that.
  • Animal Motifs: Swallows. They signify happiness, which could be interpreted as him being Wei Wuxian and Lan Wangji’s "joy" as their (unofficially) adopted son; and they signify new life, much like how he was once Wen Yuan, then after the First Siege he was taken in by Lan Wangji and lived from then on as Lan Sizhui. Swallows are also associated with peace, loyalty, and most importantly, love — all of which play a part in Lan Sizhui's personality, backstory, and connection to the main protagonists.
  • Awful Truth: The reason Lan Wangji didn't tell him of his past, and why Wen Ning also kept quiet even after finding out who he really is; although both agree that it's only a matter of time until he remembers. Eventually, this trope is averted as he takes the truth of his origins relatively well. While he does get emotional when he reveals what he knows to Wei Wuxian, it's portrayed in a positive and heartwarming light.
  • Butt-Monkey: Downplayed as Wen Yuan. While Wei Wuxian loved him and doted on him, he also liked to tease the boy and made him a frequent victim of his antics.
  • Character Development: Downplayed. His personality doesn't really change, but his time with Wei Wuxian causes him to be a bit more expressive about his thoughts and feelings, especially after he regains his past memories.
  • Cheerful Child: Not that he lost his cheerfulness when he grew up, but when he was a toddler he was this to a tee.
  • Children Are Innocent: Lan Sizhui, Wen Yuan at the time, is the best example of how the Wens that Wei Wuxian rescued from Qiongqi Path had no blood on their hands and didn't deserve the cruelty that was inflicted on them. In the audio drama, Lan Wangji convinced Lan Qiren to let him adopt Wen Yuan by invoking this trope.
  • Cuddle Bug: When he was still a child, he would latch himself onto anyone he liked by hugging their legs.
  • Cuteness Proximity: As a child, he squealed happily when Lan Wangji took him to feed the rabbits and play with them.
  • Does Not Like Spam: One of the audio drama extras reveals that he doesn't like radishes. Funnily enough, this could be due to the fact that Wei Wuxian used to argue with Wen Qing that he hates radishes so they should plant potatoes to eat instead. Although given that radishes were one of the few things that could grow in the Burial Mounds, he could have just grown to dislike it.
  • Embarrassing Old Story:
    • At the end of the novel, Wei Wuxian recounted a story about Lan Sizhui when he was still Wen Yuan when he was young and called Lan Wangji "dad" in public, clinging to his legs and crying while surrounded by a crowd of disapproving onlookers. Sizhui reacted as one might expect.
    • There's also the stories about burying your kids in mud to make them grow taller, and burying them in a pile of rabbits... just because.
  • Everyone Has Standards: While he's courteous and gentle to everyone, he's not immune to feeling annoyance towards people who exhibit terrible behavior. In the Gate-Crashing extra, he expresses his negative but honest opinion about the person he's helping, and how said person deserved a few more punches from the fierce corpse who settled his unfinished business with the former with only one punch.
  • Foil:
    • To Jin Ling. Their Establishing Character Moment shows that their personalities easily contrast; Lan Sizhui is calm, disciplined, and mature while Jin Ling is quick-tempered, brash and bratty. However, both never shirk from their duties as cultivators.
      • Their sects are more or less the opposite of each other, since the Lan clansmen are defined by their practices in austerity while the Jin clansmen are defined by their lavishness and wealth.
      • They also lost their families a few years after the Sunshot Campaign, either to Wei Wuxian (for Jin Ling) or the Four Great Sects (for Lan Sizhui), and were eventually adopted by someone else. However, whereas their guardians/Parental Substitutes don't get along, Lan Sizhui and Jin Ling are on friendly terms with each other.
      • Because of how they were raised, they grew up with different outlooks towards demonic cultivators. Because of his parents' deaths and his maternal uncle's issues, Jin Ling spent his whole life harboring hatred towards Wei Wuxian, Wen Ning, and everyone who takes up demonic cultivation. On the other hand, Lan Sizhui doesn't have any bias towards any kind of person or cultivator, and even tells Jin Ling that they shouldn't judge anything/anyone without understanding the full picture. This is defined through the initial state of their respective relationship with Wei Wuxian (disguising as Mo Xuanyu).
    • Lan Sizhui and Wei Wuxian had similar childhoods. Both were Cheerful Children that lost their families to tragic circumstances when they were still young, and were eventually adopted by someone who was close to the families they lost. They barely have any memories of their families due to either sickness or trauma, but were nevertheless treated well by their guardians.
      • That being said, their experiences in the sect where they were adopted into are radically different. Whether before or after he regained his memories, Lan Sizhui never felt like an outsider as he was treated by everyone in the Lan Sect as if he was one of them, and his guardian raised him with the utmost love and care. Even after learning of his origins, he never doubted his place in the Lan Sect. Although Wei Wuxian got along with part of the Jiang family, he never felt like he truly belonged because he's aware of his presence causing further friction within said family, with the mother (and eventually the son) hating his guts. By the present time, he has distanced himself from his sect, accepting it as part of his past but no longer of his future.
  • Foreshadowing: The novel gives enough hints prior to the finale that The Reveal of Lan Sizhui's true ancestry allows the audience to figure things out before Wei Wuxian does. A few examples include:
    • In the Yi City arc, Wei Wuxian feeds spicy congee to the junior disciples who were afflicted with corpse poisoning. When Lan Sizhui tries the congee himself, he thinks that the taste evokes a sense of nostalgia. Wei Wuxian would often try to feed Sizhui with spicy food back when he was still a toddler.
    • Also in the Yi City arc; when Wei Wuxian reassures Lan Sizhui to not be scared, he remarks how Wei Wuxian is a lot like Lan Wangji in that he could feel safe around them. This can easily be attributed to his empathy and perception regarding whether someone can be trusted or not, but in truth, it's actually because his subconscious already knows that "Senior Mo" is the same person who helped care for him years ago.
    • After he and the other juniors get rescued in the Second Siege arc, he comments on how he knew that Wei Wuxian is really broke the entire time. In the past, he called Lan Wangji "Brother Rich" while poking fun at Wei Wuxian by calling him "Brother Poor".
    • When the deceased Wen refugees come back to life to protect Wei Wuxian from the corpses controlled by the Stygian Tiger Seal, one of them starts walking towards Lan Sizhui and attempts to touch him in a non-hostile manner. Wen Yuan is said to often hang out with his grandmother a few chapters prior, and the corpse that attempted to touch him is described to look small and hunched-over, a description that would perfectly describe an old woman.
    • When Wen Ning asks for his birth name, Lan Sizhui answers that it's Yuan. The Wen child that Wei Wuxian would oftentimes play with is also named Yuan. Even when spelled with different characters, this still helps Wen Ning and Wei Wuxian draw the same conclusion. Wen Ning even comments on how Lan Sizhui looks like a relative of his.
  • Forgotten First Meeting: Wei Wuxian and Lan Sizhui actually knew each other from years ago. Until the ending, he didn't know that Lan Sizhui is Wen Yuan, or that the kid who liked to eat his flute was still alive after the First Siege.
  • Green Around the Gills: While the novel never literally describes him turning green, he's revealed to get seasick easily, even though he lives up a mountain. The fact that he's the only Lan Sect disciple to have a case of seasickness hints that he's not really of Lan blood.
  • Hairstyle Inertia: His design in the donghua has him retain the hairstyle he had as a child all the way up to his teens.
  • Happily Adopted: Even before he regained his lost memories, he was aware of the fact that he doesn't remember his parents and that he was adopted into the Lan Sect by Lan Wangji. He has no problem with this whatsoever, since Lan Wangji treated him like he was his own.
  • Has Two Mommies: A gender inversion in Lan Sizhui's case, having been adopted by Wei Wuxian and Lan Wangji in all but name.
  • Infant Immortality: He was only a toddler when the First Siege occurred and he's the only Wen who wasn't killed. Not out of mercy, however, but because he was hidden away some time before the massacre occurred.
  • It's All My Fault: He feels responsible for the death of the Mo family because of the Spirit-Attraction Flags he had set up around the Mo manor. Wei Wuxian quickly assures him that he's not to blame for what happened.
  • Keigo: Lan Sizhui speaks in a formal and polite manner; and this speech pattern is kept in both the Mandarin and the Japanese dubs.
  • Last of His Kind: He's revealed to be the last surviving member of the Wen Sect.
  • Like Father, Like Son: Upon a second reading of the novel — given that by then the reader now knows how Lan Sizhui is, in a manner of speaking, related to the protagonists — one can see that he really took a lot after Lan Wangji, who raised and taught him well.
  • Living Emotional Crutch: He was implied to be this to Lan Wangji in the past. After Wei Wuxian died, Lan Wangji could not find any trace of him, but he managed to find Wen Yuan, who was alive but gravely ill. While Lan Wangji still mourned Wei Wuxian's death that he even scarred himself in anguish, the audio drama leaves hints that Wen Yuan's presence helped Lan Wangji grieve in a healthier manner, since while he would still mourn, he would also make sure to properly raise Wen Yuan and given him a good happy life.
  • Meaningful Name: Invoked by Lan Wangji, who gave him his courtesy name. Sizhui means "to remember and long for" which is a hint at his status as the last Wen and as Wei Wuxian's relic.
  • Musical Trigger:
    • An unique and benevolent twist of the trope in that it's not a song but a musical instrument that serves as a memory trigger for Lan Sizhui, who remembers his past as Wen Yuan after seeing Chenqing since he often played with the flute when he was a child.
    • Played straight in The Untamed, where Lan Sizhui regains his memories while Wei Wuxian is playing Chenqing rather than from seeing the flute.
  • Nice Guy: He's gentle and mannerly to everyone, a trait which impressed Wei Wuxian since he thought every Lan clansman is stuffy and strict.
  • Not So Above It All:
    • He can't help but tease Wei Wuxian for being broke, given his excited reaction when Wei Wuxian admits to having no money.
    • While he's normally one of the more mature juniors, there are times when he fanboys along with the rest of the younger Lan disciples whenever Lan Wangji is involved.
  • Not So Stoic:
    • Lan Sizhui is usually the most level-headed and mature of the juniors, but he can still give in to anger, especially when the others are past reasoning with. He also gets easily embarrassed and can get scared.
    • He becomes unusually emotional during the Second Siege when he insists on fighting by the protagonists' side even when they told him to go to safety. This trope occurs again when he remembers who he really is.
  • Odd Friendship: While he's calm and polite, Jingyi is rather abrasive and loud. Still the two of them do get along and are usually partnered up together on night hunts. It's even implied in an extra that he lets Jingyi copy off of his papers.
  • Older Than He Looks: He may not look like it, but Lan Sizhui is actually a few years older than Jingyi even though they're roughly the same height and look youthful enough to be of the same age. The author revealed that his height is stunted due to suffering from malnutrition during his childhood.
  • Only Sane Man: When he's with the other juniors he acts this way and most of them usually defer to him when Lan Wangji or other sect leaders aren't around.
  • Orphan's Ordeal: Averted in a positive manner. See Happily Adopted above. Even after recalling his past life as Wen Yuan, he doesn't feel any anger or resentment for his family's death.
  • Paper Talisman: Among the juniors, Lan Sizhui uses this most often either to suppress spirits or start fires.
  • Quality over Quantity: Lan Wangji taught Lan Sizhui to always invoke this trope in learning the qin language. Wei Wuxian also notices this when Sizhui listed his observations of A-Qing (in her corpse form).
  • Red Oni, Blue Oni: Downplayed, but he's calmer and more stoic than Jingyi.
  • The Reliable One: Wei Wuxian sees Lan Sizhui as one among the juniors for his maturity, composure, kindness, and open mind. Likewise, Lan Sizhui returns the sentiment.
  • Rule of Symbolism: The motifs of the Lan and Wen Sects are the cloud and the sun, respectively. Lan Sizhui is secretly a Wen who got adapted into the Lan Sect (with only very few people knowing of his true lineage). This could easily be represented by the image of clouds obscuring the sun.
  • Screw the Rules, I'm Doing What's Right!: He's refined and mannerly and is, like Lan Wangji, a model disciple of his sect in every sense of the word. However, like his mentor, he'll always prioritize doing the right thing regardless of what anyone else may say about it.
  • Shipper on Deck: In the manhua he's more overtly supportive of the budding relationship between Lan Wangji and Wei Wuxian. When Lan Wangji takes Wei Wuxian back to the inn to rest, he merely looks back at the juniors without saying a word, but Lan Sizhui immediately beams and gives him a thumbs up.
  • Sins of Our Fathers: Averted. Aside from Lan Wangji, Qiren and Xichen, it's never confirmed if the other Lan clansmen know that Sizhui is of Wen blood, but there are no signs of him being treated differently whether or not they know. However, it's certain that absolutely no one else outside the Lan Sect knows the truth, given what the clans had done to the remaining Wens years ago.
  • Someone to Remember Him By: In a sense. After his birth parents died and his caretaker Wei Wuxian died, he was found and taken in by Lan Wangji, who he had met once prior to the First Siege. Lan Sizhui was essentially Lan Wangji's last connection to Wei Wuxian so it's literally this trope.
  • Something Only They Would Say: He proves to Wei Wuxian who he really is with this trope.
  • Spell My Name with an "S": His birth name both as a Lan and as a Wen read "Yuan" in romanized form, but they're written with different characters in hanzi: 愿 for the former and 苑 for the latter.
  • The Spock: Lan Sizhui is this among the three juniors (him, Lan Jingyi, and Jin Ling) due to his patient and sensible personality. Whenever the other two are close to blowing their tops, he'll always try to calm them down and act as the voice of reason.
  • Straight Man and Wise Guy: The Straight Man to Lan Jingyi's Wise Guy.
  • Strong Family Resemblance: Lan Sizhui is described to have a fair appearance, which is standard for a Lan disciple. However, both his grandmother and Wen Ning easily recognize him as one of their own when they get a good look at him, even though they last saw him thirteen years ago.
  • Tears of Joy: He cries out of mixed emotions, but mostly out of joy, when he recovers his lost memories and remembers Wei Wuxian as the "Brother Xian" who doted on him years ago.
  • Third Wheel: Being the Happily Adopted kid he is, Lan Sizhui ends up as the kid that Wei Wuxian and Lan Wangji drag out together the most often for extra training. Most of this extra training ends up being to leave the elders alone for their time together, making excuses to irate clients, tending to the donkey, and lying about when the elders would rise for the day... everyday.
  • Those Two Guys: He and Jingyi are rarely seen apart, and they are often paired together when they go night-hunting.
  • Token Mini-Moe: Most of the Wens that Wei Wuxian rescued consist mostly of adults or the elderly... except for Wen Yuan, who was only around two to three years old at the time.
  • Trademark Favorite Food: In The Untamed, he jokes to Wen Ning that since he always fed Lan Wangji's rabbits when he was a child, he's become very fond of carrots.
  • Tragic Keepsake: In The Untamed, he kept the paper butterfly that Lan Wangji bought for him when he was a child.
  • When All You Have Is a Hammer...: In The Living Dead, he uses his guqin to knock enemies back.
  • Wise Beyond Their Years: He holds himself up with great maturity and has a good handle on how to interact with adults in strenuous situations. He's also the de facto leader amongst the juniors whenever the other adults aren't around.
  • Wistful Amnesia: Not so evident in the novel, but this trope is played up in the Live-Action Adaptation where he has instances of recalling the blanks in his memory and not being able to figure out what or who he's forgotten.

"I would rather be eaten by a monster on a night-hunt than starve to death here!"

The second younger-generation cultivator that Wei Wuxian meets. Cheerful but brash, Lan Jingyi tends to end up talking without a filter.

  • Adaptational Personality Change: Downplayed. Lan Jingyi is still the same Hot-Blooded young boy in The Untamed, but there is an extra layer of sass added to his personality in the series.
  • Berserk Button: It's mostly Played for Laughs, but do not disrespect or harass Lan Wangji in his presence.
  • Book Dumb: Part of his lack of smarts can be attributed to childish naivete, but the From Night to Morning extra note  shows that Lan Jingyi is definitely no honor student. His reports were graded yi note , and Wei Wuxian's comments imply that he's the only one to get that score when reports were already the revised version. Jin Ling even refers to him as the dumb one in the Iron Hook extra. It's also hinted at in one extra that he copies off of Lan Sizhui's papers.
  • Brutal Honesty: He's completely frank about his opinions on anything and anyone, and either Lan Wangji or Lan Sizhui has to remind him that talking behind people's backs is against the rules. Lan Jingyi counters to Sizhui that he's not back-talking since he can also express his opinions to the person's face.
  • Combat Parkour: In the donghua, he incorporates flips into his fights, such as when he jumps over Jin Ling, flips and then kicks him in the back.
  • Cowardly Lion: Despite his fear of ghosts, Lan Jingyi never walks away from a fight. And any fear he has of the supernatural is nonexistent when he's confronting figures of authority.
  • Deadpan Snarker: Unlike the other Lan disciples, Lan Jingyi makes constant sarcastic remarks on people he doesn't like, and even when asked to tone it down he will still be brutally honest about his thoughts.
  • Fanboy: He gets extremely excited over the Twin Jades of Lan, particuarly Lan Wangji, when they come to save the juniors from a headless and undead Nie Mingjue. And earlier, Lan Jingyi immediately gets offended when Wei Wuxian hesitates on answering if he thought Lan Wangji was awesome.
  • Friend to All Living Things: Downplayed since Lan Jingyi isn't seen interacting with many animals, but he helps take care of the rabbits that Lan Wangji owns. When Wei Wuxian suggests eating said rabbits, Lan Jingyi immediately stands in front of the fuzzy creatures with a protective stance.
  • Hero-Worshipper: He highly respects Lan Wangji and at times takes the opportunity to express how great he his. He even gets upset when he thinks that Wei Wuxian doesn't have the same opinion before he was reassured otherwise.
    Lan Jingyi: Of course Hanguang-Jun is good. He just never likes to show it off. He is very low-key, right?
    Wei Wuxian: (confused) Are you asking me? Why are you asking me?
    Lan Jingyi: (angered) So you think that Hanguang-Jun is not good?!
  • Hidden Depths: While he can be a bit Book Dumb and oblivious at times, there are other times when he can be observant, such as when he suspects that "Mo Xuanyu" may not be crazy after all. He's also the first to note that the "blind" ghost girl in Yi City might not be actually blind because of how fast she moves, since real blind people usually have to watch their steps and walk slowly.
  • Hot-Blooded: He's quite excitable, expressive, and has a short fuse, making him a rather atypical disciple of the Lan Sect.
  • Hypocritical Humor: He tends to berate Wei Wuxian for breaking rules... when he's unknowingly doing the same thing himself. One infamous example would be him shouting, "Noise is prohibited in the Cloud Recesses!"
  • Ironic Fear: Despite being a cultivator who slays monsters and evil spirits for a living, he is afraid of ghosts. But he can set aside his fear when fighting.
  • Jerk with a Heart of Gold: Downplayed. He's outspoken and quick to anger, but he's not really unpleasant nor does he act like an ass to others for the heck of it. Despite being often annoyed or exasperated with Wei Wuxian, Lan Jingyi acknowledges his skills, appreciates his help, and never hesitates to speak up for him or defend him from other people.
  • Kid Has a Point: His lack of filter tends to have him drop quite a few indisputable truths.
    • He defends Wei Wuxian from a second strike from Jiang Cheng's Zidian by stating that Zidian wouldn't fail to expel a spirit from the body its possessing with its first strike. He's not wrong, since Wei Wuxian's spirit isn't technically possessing Mo Xuanyu's body, since it was Mo Xuanyu's choice to summon Wei Wuxian back into the mortal world.
    • In The Untamed, he makes a similar defense, but in the series, Jiang Cheng retorts how he's so sure that Wei Wuxian is truly dead. Lan Jingyi simply counters that Jiang Cheng is the one who killed him, so he's the one who should be sure about that. The part where Jiang Cheng is responsible for Wei Wuxian's death is half-true at best, but it's still hard-hitting enough to stun Jiang Cheng into silence.
  • No Badass to His Valet: Lan Jingyi might be brash, but he is respectful to his sect, be it his fellow juniors or the senior cultivators. However, when it comes to the cultivators who aren't of the Lan Sect, he talks to them like their rank is of no concern to him. He may address them with the proper title and talks in a fairly formal manner, but he will not hesitate to sass them if he feels it's warranted, and he's clearly not intimidated by their reputation or status.
  • No Indoor Voice: Even though he's from a clan that's been raised all their lives to restrain themselves, Lan Jingyi is unable to restrain the volume of his voice when he gets passionate or angry.
  • Not So Above It All: While he's vocal towards Wei Wuxian about following the Lan Sect's rules to anyone when they were in the Cloud Recesses, Lan Jingyi is actually eager to try things that he wouldn't be able to do back home, such as drinking wine and gorging on meat.
  • Odd Friendship: Sizhui is patient and diplomatic, whereas Jingyi is impulsive and blunt with his words. Nevertheless, the two get along well and never argue.
  • Peek-a-Bangs: His bang would almost cover his left eye if it was positioned closer to the center of his face.
  • Plucky Comic Relief: Downplayed. He's one of the very, very few characters who doesn't have any personal baggage, and his Hot-Blooded and candid nature causes him to provide several of the novel's moments of levity. However, that's not his only role in the story; as he gets involved in several hairy situations and pulls his own weight almost as much as he mouths off priceless remarks.
  • Red Oni, Blue Oni: Downplayed, but he's far more hotheaded and temperamental than Sizhui.
  • Screw the Rules, I'm Doing What's Right!: His first few interactions with Wei Wuxian have him harping about what's not allowed in the Cloud Recesses, which makes Lan Jingyi come across as a Hot-Blooded Principles Zealot. However, the Second Siege arc shows that he's not afraid of saying the truth or defending a falsely accused person, even if it means going against the wishes of his elders.
  • Shipper on Deck: While Lan Jingyi didn't like how Wei Wuxian initially kept on harassing Lan Wangji, he doesn't object when he sees that the two may actually have eyes for the other, and at one point he even expected them to act more like a lovey-dovey couple.
  • Static Character: Lan Sizhui and Jin Ling, who have some relation to the protagonists, have more prominence in the plot. By contrast, Lan Jingyi doesn't, which causes him to slightly become this trope.
  • Straight Man and Wise Guy: The Wise Guy to Lan Sizhui's Straight Man.
  • Thinks Like a Romance Novel: He exhibits this trope during the Yi City arc.
    Wei Wuxian: Hanguang-Jun, it's up to you now. We're gonna go ahead!
    Lan Jingyi: That was it? You're not going to say anything else?
    Wei Wuxian: What else do you want me to do? What else should I say?
    Lan Jingyi: Why didn't you two say, "I'm worried about you. I'm staying!", "Go!", "No! I'm not going! If I'm going, you're going with me!"? Isn't it a must?
  • Those Two Guys: He's rarely seen without Sizhui by his side, and the two are often paired together when they go night-hunting.
  • Undying Loyalty: To his sect and to anyone he considers a friend. He'll go out of his way to protect them physically and verbally.
  • Vitriolic Best Buds: While they won't acknowledge it easily, he is friends with Jin Ling and it's shown through their several snark-filled conversations.
  • You Are Fat: Played for Laughs. Lan Jingyi makes this insult about Jin Ling's dog after Jin Ling mocks the name of Wei Wuxian's donkey, to Jin Ling's irritation. It's unknown if Lan Jingyi is just joking or Fairy is being overfed, but Jin Ling claims that his dog is in good shape.

    Qingheng-Jun (青蘅君) 

Qingheng-Jun was the previous leader of the Lan Sect, and the father of the Twin Jades of Lan. He died some time after the Wen Sect attacked the Lan Sect and burned down the Cloud Recesses; but even when he was still alive, no one saw him much.
  • All Love Is Unrequited: According to Lan Xichen, while it was Love at First Sight for Qingheng-Jun when he met Madam Lan, she didn't return his feelings.
  • Foil: To Jiang Fengmian. They're both sect leaders and the patriarchs of their respective families, were killed by the Wens when their homes were attacked, and were noted to be distant from their children. However, Qingheng-Jun distanced himself from his family because of his guilt in marrying his wife and the circumstances that led to their elopement; whereas Jiang Fengmian's strained relationship with his children is partly caused by his own rocky relationship with his wife due to their contrasting temperaments and how he was forced to marry her.
  • Killed Offscreen: When the Wens attacked the Lan Sect, Qingheng-Jun got severely injured in the fight and eventually died some time after.
  • Love Makes You Crazy: The rest of the Lan clan believed this happened with Qingheng-Jun regarding Madam Lan. Want to know the whole story? He fell in love with her, but she killed his teacher. Heedless of the repercussions, he brought her back to the Cloud Recesses, did the ceremony, and threatened the elders to take her over his dead body. Then, Honor Before Reason made him seclude himself in the Cloud Recesses and never share a bedroom with her.
  • No Name Given: Title aside, his name was never revealed.
  • Posthumous Character: In The Untamed, since he was dead long before the Wen Sect burned down the Cloud Recesses.
  • The Unseen: While Madam Lan gets a brief appearance in the audio drama and in The Untamed via a flashback, Qingheng-Jun doesn't appear in any adaptation of the novel.
  • Worf Had the Flu: In the donghua, according to Jin Guangshan, Qingheng-Jun is a master in cultivation; yet he easily succumbed to his wounds when the Wen Sect razed the Cloud Recesses. This is because Qingheng-Jun spent the past few years in seclusion (and not to strengthen his cultivation), which meant he wasn't in his prime when the Wens attacked.

    Madam Lan (蓝夫人) 

Voiced by (Mandarin): Yue Yeqiao (audio drama)

Click here  to see Madam Lan in The Untamed

Qingheng-Jun's wife, and the mother of the Twin Jades of Lan. Like her husband, Madam Lan was rarely seen by anyone even within the Lan Sect, as she was said to have been bedridden with an illness. However, unbeknownst to many, the truth is a lot graver and proves that even the righteous Lan Sect has its own share of dark secrets.
  • Adaptation Deviation: In The Untamed, the Silent Room was originally Madam Lan's residence and Lan Wangji started living in the house some time after her death. But in the novel, the house where she lived in and the Silent Room are two separate places.
  • Ambiguous Situation: Even with what Lan Xichen told Wei Wuxian about his parents, it's hard to determine what's true and what's false about them, especially since Lan Xichen's own knowledge about how his parents got married is only from hearsay. Overall, it's never revealed exactly how she died or what kind of grudges Madam Lan had with the Lan Sect to kill one of them.
  • The Faceless: She makes a brief appearance in the chibi spinoff of the donghua, although everything but her face is shown to the audience.
  • Flower Motifs: Gentians, as Madam Lan lived the rest of her life in a house surrounded with said flowers. Gentians are said to symbolize sweetness or loveliness, and Wei Wuxian concluded that Madam Lan seemed to have been a gentle woman from the little he was told about her. On the other hand, gentians can also represent injustice, which is thematically present in her backstory (although what part of her story was unjust depends on the reader's interpretation) and of the novel's story as well.
  • Foil:
    • To Jiang Fengmian. One of them was (said to be) forced into the marriage, the mother in the Lans' case and the father in the Jiangs' case. However, the one who's (again, allegedly) roped into the marriage have different treatment towards their children. Madam Lan was equally kind and doting towards both her sons, whereas Jiang Fengmian was always accused of Parental Favoritism as he was more indulgent towards his ward than his biological son.
    • Madam Lan's care for her children contrasts Yu Ziyuan's. In spite of Madam Lan's mysterious history with her husband, she never treated her kids poorly and was always gentle and nurturing with them despite the limited time she gets to see them. As a result, neither Lan Xichen nor Wangji were negatively affected by their time with her and remember her fondly. Yu Ziyuan on the other hand, despite her status as a powerful cultivator and her genuine love for her children, isn't exactly the best mother or stepmother/guardian and pits both her son and her ward against each other out of resentment, leaving them with several deep-seated issues which gradually soured their relationship in the long run.
    • To Meng Shi. Both lived their lives in imprisonment; although while this is literally the case for Madam Lan due to taking a life, Meng Shi is metaphorically imprisoned by the stigma of her job as a prostitute. As a result, this affected the childhood of their sons, with Lan Xichen and Wangji growing up with the best and most stringent education and training at the cost of proper social exposure, while Jin Guangyao's potential and skill are always looked down on solely because of his mother's occupation. Additionally, Madam Lan never inquired her sons about their education, whereas Meng Shi pushed for her son to learn cultivation in the hopes that it would soon bring them prestige and fortune. In spite of everything, however, both the Lan brothers and Jin Guangyao loved their mother deeply and were loved in return.
  • Good Parents: Bloody past aside, Madam Lan was kind and gentle to both her sons despite only getting to see them once a month. In return, while both know of her history with their father, they have nothing but good memories of her.
  • Happiness in Slavery: Played with. It's ambiguous whether she agreed to marry Qingheng-Jun after she had committed a crime that would have gotten her executed by the Lan Sect or was forced into the marriage. However, Lan Xichen stated that she never had any complaints about either being under house arrest or receiving limited visits from her children.
  • Ill Girl: To the unknowing, this is the reason why she can't leave her house. The truth is that she's actually imprisoned there as punishment for killing an elder of the Lan Sect.
  • Marriage of Convenience: To a degree. Although she didn't return Qingheng-Jun's love for her, Qingheng-Jun married her to protect her from his sect's wrath after she murdered his mentor. However, guilt drove him to placed her under house arrest, and she could only see her children once a month up until her death.
  • Mysterious Past: Lan Xichen doesn't know the exact reason why Madam Lan killed Qingheng-Jun's teacher, only knowing that it had something to do with "grievances".
  • Never Say "Die": After she died, Lan Qiren told his nephews that they didn't have to visit their mother anymore, explaining that she was "gone". Lan Wangji, who was only six years old at the time, didn't catch on to what his uncle meant and continued to visit her house.
  • No Name Given: She's only referred as Madam Lan, and Lan Xichen never mentions her birth or courtesy name.
  • Posthumous Character: Madam Lan was already dead prior to the beginning of the story.
  • The Tease: The familial variant. According to Lan Xichen, she liked to tease Lan Wangji during their monthly visits.

    Lan Yi (蓝翼) 

Voiced by: Lu Gengyi (live-action)
Played by: Lee Yeuk-Tung note  (live-action)

Click here  to see Lan Yi in The Untamed

The third (and only female) leader of the Lan Sect. She's also the granddaughter of Lan An, the founder of the Lan Sect.
  • Action Girl: She's the only woman in the Lan Sect to become its leader, and founded her clan's signature Razor Wire technique. She's also the other only female cultivator besides Baoshan Sanren to become a sect leader.
  • Adaptation Expansion: Her name is only mentioned a few times in the novel, but she makes an official appearance in The Untamed.
  • Advertised Extra: Months before The Untamed aired, she's one of the twenty-four characters who got a promotional poster. However, in the series proper she only appears for two episodes (or runtime-wise, about half an episode's length).
  • Bunny-Ears Lawyer: Like Wei Wuxian said, Lan Yi is considered an outlier by the Lan Sect, yet her skills couldn't be denied.
  • Friend to All Living Things: In the live-action series, she trapped herself in a cave to seal the shard of the Stygian Iron she had with her. For company, she kept a few rabbits with her before Lan Wangji adopted them and cared for them.
  • Musical Assassin: The original one of the Lan Sect since she created the Chord Assassination technique, and the skill's main purpose is to silence any dissenters.
  • Not So Different: She and Wei Wuxian are very much alike. Both are seen as eccentrics due to founding a practice that's widely frowned upon, albeit no one doubted their power and authority and ended up learning the arts they created. The Untamed adds more by having Lan Yi attempt to harness the power of the Stygian Iron before it got the better of her, which mirrors Wei Wuxian's attempt to fully control his demonic cultivation.
  • Posthumous Character: She had already died since decades ago, and her name is only brought up a few times when Wei Wuxian brings up either the Chord Assassination technique (which she founded) or her reputation in the Lan Sect. Even when she makes an official appearance in The Untamed, she remains dead and only appears to Wei Wuxian and Lan Wangji as a spirit.


How well does it match the trope?
