Wanted to contribute but then I don't recall much on Xianxia/Wuxia.
This is difficult task but be aware how repetitive the enemies/luck are.
Its not just young master/higher up but include more variety.
Can be crazy unorthodox, weak thug, betrayal, bully, impatient beauty, enemy of my enemy is a friend.
In terms of luck can be replaced with barter, bribe, gift, hint, technique.
In Chinese there is something about describing someone and the more variety to add in terms of face/body shape, tone, imperfection, pose, clothing...
This is fatty, he ate breakfast of 5 man, like a pig that drench in sweat with pimples that looks horrendous but nevertheless has the strenght of a raging bull capable of catalpulling a man 500 metres by his bulging belly. Wearing thick jacket and oversized pants which wanted to rip, thankfully it was just stretching thanks to superior material.
On the other hand, 4 eyes is a quiet reserved person who do not bother with insult and yawns all day. His main income is being a bookwormer teaching impatient kids that looks far filled then his thin bamboo stick like body. Food is from the wild and malnutrition and infection feels like coming close, no worries as he smiles brilliant like a scheming duck.
Naming has traits you should consider.
This sect revolves on solving justice with sword, Wǔlì(Sword) Yì(Justice) sect.
