* RevisedEnding: WordOfGod says that during early stages of development, the story had two possible endings. Neither of them were chosen for the final ending.
** In one ending, it would follow exactly like canon, with Shen [[spoiler:dying after being crushed by the cannon]] and Lianne [[spoiler:going onto the lake to have the moon reunite her with her beloved, with her not being pregnant]]. This ending was more ambiguous, but also a heavily implied [[DownerEnding tragedy]].
** In another, much longer draft, Shen would have [[spoiler:survived the cannon fall, like in the finished story. However, he would have been saved by monks with his body crippled, and he went into self-imposed exile]]. Lianne would have stayed in her father's home to [[spoiler:raise her son alone, as she believed Shen to be dead. However, when a mercenary group attacked the Shan Palace, Lianne was forced to flee with her son and was later reunited with Shen when he came to their rescue]].
* WhatCouldHaveBeen:
** The WordOfGod has it that the story was originally going to be a crossover with ''WesternAnimation/TheSwanPrincess'', but the author abandoned the idea to suit the story's purposes better.
** Before deciding the title, the author pondered between ''The Vow'' and ''China Moon'', as explained [[http://adonovan94.deviantart.com/art/Vow-Concept-439465377 here]].
