Spent the afternoon doing small home repair so here SMALL HOME REPAIR HEADCANONS 
wwx is like the diy king, he can fix anything using just what he has lying around, he can watch like half of a home repair yt and understand exactly where it's going, like some kind of small home repair prodigy
He knows his chemistry so understands exactly how to combine two things to get something else, make a perfect adhesive, make a product that scours any surface, ALSO he has a home welding kit in his garage, just from, you know, random stuff he's had to do
Imagine little a-yuan sitting beside him while he's diy plumbing the bathroom sink, handing wwx tools when wwx asks for them, knows all the names for the tools, says things like 'channel lock wrench' in his tiny little 4 year old voice
I'm thinking nhs runs wwx's home repair yt account, where these vids are like flawlessly edited, but wwx doesn't actually know that nhs is doing this
Therefore, wwx's small home repair yt channel is like, a huge hit, he's the zany host and he doesn't know it. He's well known for like being an absolute miracle worker, and also sometimes he DOES get wild with a blowtorch so that's always fun to watch
I think lwj just sorta hangs out and makes everyone lemonade, and/or horny grips whenever wwx gets smudges of dirt on his cheeks and nose
ON THE OTHER HAND I think hualian LOVES diy home repair projects not ENTIRELY because hc loves watching gege destroy things with his Big Muscles, but it's definitely a consideration
Xie lian is the kind that gets so far into a project and realizes that there are like 30 sub-projects that are necessary, like he started out replacing a sink and ended removing a wall
Hua Cheng hands him the sledgehammer to get it done
Sometimes hc will just do the project if it's a present for gege, but other times he knows xl just likes to tinker
