LOL, that's a surprisingly accurate description of everyone! Here, have Nihuang and Investigator Awesomesauce (Xia Dong)! The only person you're missing is Prince Yu, the wannabe Crown Prince who isn't whiny and has no moustache, and compensates by wearing a ton of gold.

I recall being upset when both of Guy With Two Surnames' dads turned up at the same time, since ahhh they're different people???

adisgracetoscholars might have some further info in their NIF recaps (potential spoilers), but mostly they're just "everyone wears the hair they should", AFAIK.
