Favourite Cheng Xiaoshi headcanons?

I was gonna ask later but a few came up in my LG post and I wanted to hear more!!!

A few of mine: - when he first met Lu Guang he started trying to read "literature" books to be able to talk to him about his interests - when he reunites with his parents he'll cut his ponytail off - BONUS: he tried to braid his ponytail for a while but it was too hard to reach the back of his head but QL still does it for him sometimes - this boy is a food vacuum he Can and Will eat anything
