History Characters / GrandmasterOfDemonicCultivationMoDaoZuShiLanClanOfGusu

* DressCodedForYourConvenience: Recognisable by their white uniforms and forehead ribbons, which Wei Wuxian compares to mourning clothes. Blood descendants of the Lan Clan also have the blue cloud motifs on their ribbons.

* AdaptationalNiceGuy: The ''donghua'' keeps the scene where Lan Xichen tells Wei Wuxian about [[spoiler:how Lan Wangji got the scars on both his back and his chest]]. However, the circumstances behind the scene paint him in a far less harsher light. In the novel, Lan Xichen tells Wei Wuxian what happened in a fit of frustration due to [[spoiler:the mistaken assumption that Wei Wuxian was toying with Lan Wangji's feelings, and caps it off by coldly telling him that he is the worst mistake his younger brother has made]]. On the other hand, Lan Xichen's motive for telling Wei Wuxian the truth in the ''donghua'' is to [[spoiler:make the latter realize just how much he truly means to Lan Wangji, out of fear that he's going to leave his brother's side]]. While Wei Wuxian [[spoiler:has zero intentions to leave Lan Wangji]], he does realize and understand why Lan Xichen told him everything.

*** In the ''donghua'', while Wei Wuxian's antics drove him up the wall as a teen, he approved of Lan Wangji's decision to [[spoiler:find and shelter him and the Jiang children after the Wen Clan's attack on Lotus Pier]] which showed he had at least some level of concern for the young man.
*** He was less harsh towards Wei Wuxian while he taught him at the Cloud Recesses. In the present timeline, he's also not as obstructive towards him as he is in the novel; during the Second Siege he remarks that he should have known sooner that "Mo Xuanyu" was Wei Wuxian but otherwise shows no hostility towards him, and in the finale [[spoiler:he even takes his and Lan Wangji's advice seriously and helps foil Jin Guangyao's plans by disabling the arrays around Yunping City]].

* BeautifulAllAlong: Downplayed. He looks younger and more handsome without his beard according to Creator/MoXiangTongXiu, but this is only implied in the novel at best as he's very attached to his beard (if his anger when Wei Wuxian cut it off in an audio drama extra is any indication) and never seen without it. However, a quick ''manhua'' flashback panel does show him clean-shaven when his nephews were young children, and he looked similar to how his nephews would turn out as adults.

* JerkassHasAPoint: When a teenage Wei Wuxian suggested that using resentful energy is no different from using spiritual energy, Lan Qiren rebutted that he couldn't be sure that he could completely control resentful energy and ensure that it wouldn't backfire on him. Although he reacted more angrily than necessary, his words were an ominous foreshadowing of Wei Wuxian's demise.

* HasTwoMommies: A gender inversion. Lan Wangji raised him and Wei Wuxian [[spoiler:(who previously took care of himm) also becomes a father figure following their marriage, making them his parents in all but name]].

* RedOniBlueOni: Downplayed. He's calmer and and more polite than the snappy Lan Jingyi.

* RedOniBlueOni: Downplayed, but as the Red Oni he's far more hotheaded and temperamental than the calm Sizhui.

* KilledOffscreen: When [[spoiler:the Wens attacked the Lan Clan]], Qingheng-jun was severely injured in the fight and eventually died some time after.

* UnwantedSpouse: Downplayed. [[spoiler:Madam Lan didn't love him back but still had a MarriageOfConvenience with him since she would had otherwise been hunted down by the Lan Clan. It is unknown if she ever returned his feelings or not, especially after she was basically imprisioned by him.]]

* StaticCharacter: Lan Jingyi mainly serves as a comedic character who gets dragged into the plot and supports the protagonists throughout the story, hence he doesn't receive any significant development by the epilogue.

* GenerationXerox: Despite the clan's conservative ways, Qingheng-jun and his sons all have a fiercely loyal and passionate side when their loved ones are involved. This seems to go all the way back to the first leader Lan An, who found the Lan Clan after meeting his cultivation partner; he came up with the clan's forehead ribbon and its significance when touched by the clansman's "fated person", and returning to the temple for the remainder of his life after his partner's death implies he was devastated.

* BrokenAce: Lan Xichen is powerful and wise, and 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. However, finding out [[spoiler:Jin Guangyao has done a lot of crime]] stresses him out and sends him into turmoil as the story progresses. By the epilogue, [[spoiler:he's a grieving recluse due to his sworn brother's demise, with Lan Wangji noting he's not doing so well]]. In the "Banquet" extra, Wei Wuxian observes that Lan Xichen seems to be neglecting his health and has become somewhat absent-minded.

* NiceGuy: He's gentle and mannerly to everyone, a trait which impresses Wei Wuxian since he initially thinks every Lan clansman is stuffy and strict.

* BookDumb: Downplayed. He's not a terrible student, but he's implied to be less bright than his peers according to the Lans' strict standards. In the "From Night to Morning" extra, his reports are graded ''yi''[[note]]the Chinese equivalent of "B"[[/note]] and Wei Wuxian's comments imply that he's the only one to get that score when said reports were already the ''revised'' version. In the "Iron Hook" extra, Jin Ling refers to him as the dumb one and it's hinted that he copies off of Lan Sizhui's papers. He nevertheless keeps up with the juniors during their adventures and behaves as one would expect from a Lan clansman.

* {{Hypocrite}}:
** Lan Xichen tells Wei Wuxian that his brother's worst mistake was falling in love with him, except that he's actually the one deserving of the same criticism since [[spoiler:he trusted and sided with [[VillainWithGoodPublicity the wrong guy]]]]. And unlike Lan Wangji, who [[spoiler:sees both the good and bad in Wei Wuxian, Lan Xichen tries to keep seeing only the good in Jin Guangyao]].
** At Guanyin Temple, he warns Jiang Cheng to not listen to anything [[spoiler: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.

* MoralityPet: He may be the only person [[spoiler:[[BigBad Jin Guangyao]]]] has never thought about harming.

* OddFriendship: At first glance, it would be difficult to imagine Lan Xichen and Nie Mingjue getting along due to their opposing personalities, but the two were quite close to the point they even became sworn brothers. It's due to this friendship that Lan Xichen has been looking after Nie Huaisang ever since his sworn brother's untimely passing.
* PacifismBackfire: He's reluctant to 1) take sides, 2) take more extreme but necessary actions, and 3) believe any damning information about the people he's personally close to, and blood has been shed due to this. 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.

* AdaptationalBadass: While he's stated to be an all-around skilled cultivator, he gets a few more opportunities to show off his abilities in the adaptation.

'''Voiced by (Japanese):''' Mitsuhiro Sakamaki (animation), Creator/TarusukeShingaki (audio drama)\\

* WorfHadTheFlu: Lan Xichen is one of the strongest cultivators in the series and can easily subdue his opponents. In the climactic arc of the ''donghua'', however, he has to regain his spiritual powers by forcefully breaking the seal prior to encountering [[spoiler:Nie Mingjue's corpse]], leaving him to struggle during the fight due to his injuries and lack of usual strength.

* WorfHadTheFlu: In the ''donghua'', Lan Xichen struggles a lot more in helping Wei Wuxian and Lan Wangji in the final arc. Whereas he waited for the seal on his meridians to wear off in the novel, he forcibly breaks the seal in the AnimatedAdaptation, which leaves him both injured and not at his full strength.

* UnwantedSpouse: [[spoiler: Madam Lan didn't love him back but still had a MarriageOfConvenience with him since she would had otherwise been hunted down by the Lan Clan. It is unknown if she ever returned his feelings or not, especially after she was basically imprisioned by him.]]

* IllGirl: Subverted. Most of the Lans believe that poor health was the reason why she couldn't leave her house. The truth is that [[spoiler:she was actually imprisoned there as punishment for killing an elder of the Lan Clan]].

* TheDreaded: She originally created Chord Assassination technique to kill dissidents, resulting in criticism both from her own clan and the cultivation world as a whole.

* The Dreaded: She originally created Chord Assassination technique to kill dissidents, resulting in criticism both from her own clan and the cultivation world as a whole.

Qingheng-jun was the previous leader of the Lan Clan, and the father of the Twin Jades of Lan. He died some time before the start of the Sunshot Campaign -- and even when he was still alive, no one saw him much.

* PosthumousCharacter: He's already dead when the story begins, as he [[spoiler:succumbed to his injuries from the the burning of the Cloud Recesses]] in the flashback arc. ''Series/TheUntamed'' takes it a step further by making him already dead when Wei Wuxian started studying in Gusu.
* UnnamedParent: He's the father of the Twin Jades, but his name is never stated.
* UnwantedSpouse: [[spoiler:Downplayed. Madam Lan didn't love him back but still had a MarriageOfConvenience with him since she would had otherwise been hunted down by the Lan Clan. It's unknown if she ever returned his feelings or not.]]

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 Clan, 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 Clan has its own share of dark secrets.

* DeceasedParentsAreTheBest: 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. Despite being one of the few good parents in the story, she died when her children were still young.
* FlowerMotifs: Madam Lan lived the rest of her life in a house surrounded with gentians. These flowers 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 implied in her backstory.
* IllGirl: Most of the Lans believe that poor health was the reason why she couldn't leave her house. The truth is that [[spoiler:she was actually imprisoned there as punishment for killing an elder of the Lan Clan]].

* NoFullNameGiven: She's only known as Madam Lan.
* PosthumousCharacter: Madam Lan was already dead prior to the beginning of the story.
* UnnamedParent: Despite being the mother of one of the protagonists and another major character, she's only referred to as Madam Lan.

The third (and only female) leader of the Lan Clan. She's the granddaughter of Lan An, the founder of the Lan Clan.

* ActionGirl: She's the only woman in the Lan Clan to become its leader, and founded her clan's signature RazorFloss technique. She's also the only other known female cultivator besides Baoshan-Sanren to become a clan leader.

* PosthumousCharacter: As the third founder of the Lan Clan she died well before the story, 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 Clan. While the teenage Wei Wuxian and Lan Wangji met her in ''Series/TheUntamed'', she was only there as a spirit.

* AdaptationalAngstUpgrade: Inverted. In the finale of the ''donghua'', Lan Xichen is shown to be in grief from [[spoiler:knowing the truth about Jin Guangyao's crimes and subsequently losing him]], with some of the people commenting that it will take time for him to recover from what had happened. However, his emotional turmoil is not too crushing that [[spoiler:he goes into seclusion]], which is what ends up doing in the novel.

* PosthumousCharacter: Unlike the novel and its other adaptations, in ''Series/TheUntamed'' he's dead prior to the story and long before [[spoiler:the Wen Clan burned down the Cloud Recesses]].

* WorfHadTheFlu: According to Jin Guangshan in the ''donghua'', Qingheng-jun was a master in cultivation. Yet he easily succumbed to his wounds when [[spoiler:the Wen Clan razed the Cloud Recesses]]. This is because he spent the later stages of his life in seclusion [[spoiler:(and ''not'' to strengthen his cultivation)]], which meant he wasn't in his prime when [[spoiler:the Wens attacked]].

** 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 the former when he tells him about [[spoiler:the events at the Nightless Imperial Capital and what Lan Wangji went through for him]], even telling him point-blank that [[BrutalHonesty he's the only mistake his younger brother has ever made]].

* AmnesiacHero: He has no memories of his early childhood, meaning he doesn't remember [[spoiler:his Wen family and being under Wei Wuxian's care]]. Granted, getting a high fever as a toddler would have encouraged that. [[spoiler:He finally gets his memories back after they're triggered by the sight of Chenqing in the finale, and accompanies Wen Ning to the Nightless Imperial Capital to bury their family's ashes and build a cenotaph for Wen Qing.]]

** He's respectful of his elders, but he sometimes shows his amusement at Wei Wuxian's expense. Such examples including laughing when the latter's cooking is insulted and when he jokes about the older man being too broke.

** He remains stern in the ''donghua'' but is less unpleasant:
*** He's given more facets to his character than just being the archetypal pedantic, strict, and uncompromising mentor and uncle figure.
*** He was less harsh towards Wei Wuxian while he taught him at the Cloud Recesses. In the present timeline, he's also not as obstructive towards him as he is in the novel; during the Second Siege he remarks that he should have known sooner that "Mo Xuanyu" was Wei Wuxian but otherwise shows no hostility towards him, and in the finale [[spoiler:he even takes his and Lan Wangji's advice seriously and helps foil Jin Guangyao's plans by disabling the array]].

* HonorBeforeReason: He usually prioritises honor over anything else no matter how absurd it is, although he'll take a step back in life-or-death matters where he knows acting on his prejudices would only worsen the situation.

* IronicName: The ''qi'' in his name translates to "to start/ open" while the ''ren'' translates to "benevolence". Together, his name means "to open benevolence". While he's not a morally corrupt character, he is biased and completely set in the old and narrow-minded ways, which plays a part in the strict manner he raises his nephews. While it's well-intentioned and comes with some benefits, it also has its fair share of negatives, as his nephews are left almost completely ill-equipped to properly handle more complex scenarios that require in-depth social knowledge and understanding of human nature. This does not bode well for them later on, as reflected in [[spoiler:Lan Wangji's difficulty in properly getting himself across to Wei Wuxian and Lan Xichen's near-blind trust in Jin Guangyao]].

* JerkassHasAPoint: When a teenage Wei Wuxian suggested that using resentful energy is no different from using spiritual energy, Lan Qiren rebutted that he couldn't be sure that he could completely control resentful energy and ensure that it wouldn't backfire on him. Although he reacted more angrily than necessary, his words were ominous foreshadowing of Wei Wuxian's demise.
* KarmaHoudini: Downplayed. He was one of the participants of the First Siege, an event that saw the deaths of both [[spoiler:the Wen survivors]] and Wei Wuxian (a man he still demonises in the present). However, like everyone else, he doesn't get any legal nor karmic punishment for it (putting aside Wei Wuxian's constant presence annoying him once again the epilogue after [[spoiler:he marries Lan Wangji and starts living the Cloud Recesses]]).

** In the ''donghua'', while Wei Wuxian's antics drove him up the wall as a teen, he approved of Lan Wangji's decision to [[spoiler:find and shelter him and the Jiang children after the Wen Clan's attack on Lotus Pier]] which showed he had at least some level of concern for the young man.

* SadistTeacher: Downplayed. While his strict teachings aren't unfair and has its benefits, Lan Qiren wasn't above targeting Wei Wuxian when he briefly taught him, even the latter was fulfilling his student duties or if other students were involved in the issue.
* SkewedPriorities: While he genuinely loves hs nephews, 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. In the climactic arc, [[spoiler:even when Guanyin Temple is a mess and the two men have emotional events to deal with]], all Lan Qiren laments is that his once perfect two newphews are no longer listening to him.

* UngratefulBastard: Even though Wei Wuxian [[spoiler:helps save him and the other cultivators during the Second Siege twice over]], Lan Qiren still suspects that he has evil intentions and only barely tolerates him because of the larger situation at hand. Even long after the events of the epilogue, he continues to see him as a horrible influence on Lan Wangji in spite of [[spoiler:the two eloping and making their marriage official.]]

* AmnesiacHero: He has no memories of his early childhood, meaning he doesn't remember [[spoiler:his Wen family and being under Wei Wuxian's care]]. Granted, getting high fever as a toddler would have encouraged that. [[spoiler:He finally gets his memories back after they're triggered by the sight of Chenqing in the finale, and accompanies Wen Ning to the Nightless Imperial Capital to bury their family's ashes and build a cenotaph for Wen Qing.]]

* DressCodedForYourConvenience: Recognisable by their white uniforms and forehead ribbons, which Wei Wuxian compares to mourning clothes. Descendents of the Lan Clan also have the blue cloud motifs on their ribbons.

* {{Veganopia}}: Downplayed. One of the rules of their clan states that killing livestock is forbidden, and Wei Wuxian observes that all of their meals are purely vegetarian. However, they can consume meat outside the Cloud Recesses when eating out, as those don't require ''them'' to kill any animal.

The current head of the Lan Clan, 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 [[StrongFamilyResemblance they are very similar in appearance]]. He swore an [[BloodBrothers oath of brotherhood]] with Nie Mingjue and Jin Guangyao, and he is the middle brother. Together, they are called the Venerated Triad.

* AdaptationalNiceGuy: The ''donghua'' keeps the scene where Lan Xichen tells Wei Wuxian about [[spoiler:how Lan Wangji got the scars on both his back and his chest]]. However, the circumstances behind the scene paint him in a far less harsher light. In the novel, Lan Xichen tells Wei Wuxian what happened in a fit of frustration due to [[spoiler:the mistaken assumption that Wei Wuxian was toying with Lan Wangji's feelings, and caps it off by coldly telling him that he is the worst mistake his younger brother has made]]. On the other hand, Lan Xichen's motive for telling Wei Wuxian the truth in the ''donghua'' is [[spoiler:make the latter realize just how much he truly means to Lan Wangji, out of fear that he's going to leave his brother's side]]. While Wei Wuxian [[spoiler:has zero intentions to leave Lan Wangji]], he does realize and understand why Lan Xichen told him everything.

** 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 the former when he tells him about [[spoiler:the events at Nightless City and what Lan Wangji went through for him]], even telling him point-blank that [[BrutalHonesty he's the only mistake his younger brother has ever made]].

** He has a soft spot for Nie Huaisang (the younger brother of his older sworn brother Nie Mingjue), as he looks after him once he becomes clan 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 on his own.

* HorribleJudgeOfCharacter: Downplayed. He has unrelenting belief in [[spoiler:Jin Guangyao]] even when the evidence stacks up against the latter's innocence, right up until he's captured and held hostage by the very character. However this mistake in judgement isn't completely unreasonable, as many other men (including [[spoiler:Nie Mingjue at first]]) have also been fooled by [[spoiler:Jin Guangyao]] due to the latter's masterful acting and manipulative ways.

* ShipperOnDeck: Downplayed. Lan Xichen was aware of Lan Wangji's interest in Wei Wuxian and encouraged him to befriend him in the past. Although later resistant to the idea of the two being romantically involved, he still calls Wei Wuxian out for [[spoiler:not knowing about Lan Wangji's feelings for him sooner]] and doesn't object when [[spoiler:the two confess to each other and become a couple]], implying he's willing to be more open to it.

* NeverGetsDrunk: In this adaptation, while the Lan Clan's inability to hold their liquor is kept, Lan Xichen avoids getting drunk by using his golden core to dispel the alcohol's effects in situations where he's required or forced to drink.

*** He was less harsh towards Wei Wuxian while he taught him at the Cloud Recesses. In the present timeline he's also not as obstructive towards him as he is in the novel; during the Second Siege he remarks that he should have known sooner that "Mo Xuanyu" was Wei Wuxian but otherwise shows no hostility towards him, and in the finale [[spoiler:he even takes his and Lan Wangji's advice seriously and helps foil Jin Guangyao's plans by disabling the array]].

Granted, getting high fever as a toddler would have encouraged that. [[spoiler:He finally gets his memories back after they're triggered by the sight of Chenqing in the finale, and accompanies Wen Ning to Nightless City to bury their family's ashes and build a cenotaph for Wen Qing.]]

* AmnesiacHero: He has no memories of his early childhood, meaning he doesn't remember [[spoiler:his Wen family and being under Wei Wuxian's care]]. Granted, getting high fever as a toddler would have encouraged that. [[spoiler:He finally gets his memories back after they're triggered by the sight of Chenqing in the finale, and accompanies Wen Ning to Nightless City to bury their family's ashes and bild a cenotaph for Wen Qing.]]

* DoesNotLikeSpam: One of the audio drama extras reveals that he doesn't like radishes. This is hinted to be due to the influence of his childhood, [[spoiler:as radishes were one of the few things that could grow in the Burial Mounds and Wei Wuxian would argue with Wen Qing about whether to plant them or potatoes]].

* ForgottenFirstMeeting: Wei Wuxian and Lan Sizhui actually knew each other from years ago. [[spoiler:Until the ending, the older man doesn'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]].

* LivingEmotionalCrutch: He was implied to help Lan Wangji keep it together in the past. [[spoiler:After Wei Wuxian died, Lan Wangji could not find any trace of him, but he managed to find a gravely ill Wen Yuan. While he still mourned his loved one's death and even scarred himself in anguish, the audio drama leaves hints that the child's presence helped him grieve in a healthier manner, since while he would still mourn, he would also make sure to properly raise Wen Yuan -- now Lan Sizhui -- and give him a good happy life.]]

* NiceMeanAndInBetween: Lan Sizhui is the nicest out of himself, Jin Ling (the rudest and most temperamental) and Lan Jingyi (friendly but also often runs this mouth).

** While he's normally one of the more composed juniors, he can exhibit a more childish side. There are times when he fanboys along with the rest of the younger Lan disciples whenever Lan Wangji is involved, and not even he's immune to joining a brawl.

* RaisedByTheCommunity: [[spoiler:During his time at the Burial Mounds, he was raised by his grandmother, the other Wen remnants and Wei Wuxian.]]

* BookDumb: Downplayed. He's not a terrible student, but he's implied to be less bright than his peers according to the Lans' strict standards. In the "From Night to Morning" extra his reports are graded ''yi''[[note]]the Chinese equivalent of "B"[[/note]], and Wei Wuxian's comments imply that he's the only one to get that score when reports were already the ''revised'' version. In the "Iron Hook" extra Jin Ling refers to him as the dumb one and it's hinted that he copies off of Lan Sizhui's papers. He nevertheless keeps up with the juniors during their adventures and behaves as one would expect from a Lan clansman.

** 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.

* TheKirk: He's HotBlooded but also often a voice of reason. He balances out [[TheSpock the composed and sensible Lan Sizhui]] and the [[TheMcCoy easily irritable and emotional Jin Ling]].

* StaticCharacter: Lan Jingyi mainly serves as a comedic character who gets dragged into the plot and supports the protagonists throughout the story, and so doesn't receive any significant development by the epilogue.

* UndyingLoyalty: He's very loyal to his clan and to anyone he considers a friend. He'll go out of his way to protect them physically and verbally.

* LoveMakesYouCrazy: Qingheng-jun's marriage is what lead to him [[spoiler:secluding himself and putting his wife in another house for the rest of their lives. He fell in love with Madam Lan, 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 [[GoThroughMe over his dead body]]. Then, HonorBeforeReason made him seclude himself in the Cloud Recesses and never share a bedroom with her]]. Consequently, the rest of the Lan Clan believed him romantically pursuing Madam Lan was madness.

* AdvertisedExtra: For the ''Series/TheUntamed'' she was one of the 24 characters who got a promotional poster. However in the series proper she only appears for two episodes with about half an episode's length of screentime.

* ItRunsInTheFamily:
** A low tolerance for alcohol and acting bonkers after consuming any is genetic in the Lan Clan. Lan Wangji and Lan Xichen become nonsensical in different ways after mere sips, and the ''donghua'' even shows Lan Jingyi being an obnoxious drunkard while appearing far more wasted than the others.
** Despite the clan's conservative ways, Qingheng-jun and his sons all have a fiercely loyal and passionate side when their loved ones are involved.

* {{Veganopia}}: Downplayed. One of the rules of their clan states that killing livestock is forbidden, and Wei Wuxian observes that all of their meals are purely vegetarian. However, they can eat meat in meals that didn't require ''them'' to kill any animal.

* TheKirk: A deconstruction of this trope among the Venerated Triad. The rational and friendly Lan Xichen tried to play peacemaker between his sworn brothers, who had clashing personalities (Nie Mingjue being temperamental and Jin Guangyao being pragmatic). However, his inability to pick sides did more damage than good to the trio's relationship, with [[spoiler:Jin Guangyao getting away with plotting Nie Mingjue's death]].

* KarmaHoudini: Downplayed. He was one of the participants of the First Siege, an event that saw the deaths of both the Wen survivors and Wei Wuxian (a man he still demonises in the present). However, like everyone else, he doesn't get any legal nor karmic punishment for it (putting aside Wei Wuxian's constant presence annoying him once again the epilogue after [[spoiler:he marries Lan Wangji and starts living the Cloud Recesses]]).

* SternTeacher: He's infamous amongst his students (both the clan and visiting students) for his strict ways.

Lan Sizhui is one of the younger-generation cultivators that Wei Wuxian first meets after he came BackFromTheDead. The NiceGuy, 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.

* HasTwoMommies: A gender inversion. Lan Wangji raised him and [[spoiler:Wei Wuxian (who previously took care of himm) also becomes a father figure following their marriage, making them his parents in all but name]].

* LivingEmotionalCrutch: He was implied to help Lan Wangji keep it together in the past. [[spoiler:After Wei Wuxian died, Lan Wangji could not find any trace of him, but he managed to find a gravely ill Wen Yuan. While he still mourned his loved one's death and even scarred himself in anguish, the audio drama leaves hints that Wen Yuan's presence helped him 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.]]

* SomeoneToRememberHimBy: [[spoiler:After the already-orphaned Wen Yuan lost his parental figure Wei Wuxian in the First Siege along with his family, he was found and taken in by Lan Wangji, who he had met once prior. The latter's kindness and fondness for the child aside, Wen Yuan -- renamed Lan Yuan -- was essentially his last connection to Wei Wuxian.]]

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

* TheMcCoy: He's HotBlooded but also often a voice of reason. He balances out [[TheSpock the composed and sensible Lan Sizhui]] and the [[TheKirk easily irritable and emotional Jin Ling]].

->'''Leader''': Lan Xichen (current), Qingheng-Jun (past)\\

** Despite the clan's conservative ways, Qingheng-Jun and his sons all have a fiercely loyal and passionate side when their loved ones are involved.

* FoolishSiblingResponsibleSibling: He served as the Responsible Sibling to his older brother's Foolish Sibling. Following Qingheng-Jun's marriage and [[spoiler:subsequent seclusion, which caused him to neglect his duties as both a clan leader and father]], Lan Qiren took over his brother's duties. Not wanting his nephews to repeat their father's mistakes, he worked hard to raise them as well-mannered and logical cultivators.

->''"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 Jingyi''': Of course Hanguang-Jun is good. He just never likes to show it off. He is very low-key, right?\\

'''Lan Jingyi''': ''[angered]'' So you think that Hanguang-Jun is not good?!

-->'''Wei Wuxian:''' Hanguang-Jun, it's up to you now. We're gonna go ahead!\\

[[folder:Qingheng-Jun (青蘅君)]]

Qingheng-Jun was the previous leader of the Lan Clan, and the father of the Twin Jades of Lan. He died some time before the start of the Sunshot Campaign -- and even when he was still alive, no one saw him much.
