Mxtx Fanfic - Tumblr Posts

I asked this on discord and got no response so I'm just gonna try here even though I'll likely get no response here either lol

I'm planning on rewriting a fic I had began writing but never finished from like forever ago The fic has Shen Yuan's family in it but I don't actually have any names for his two older brothers, little sister and parents. In the original drafts they were all just Japanese names for some reason. Has anybody got any ideas on what to call them?
