My family is from Manchuria/Beijing where the communist party has a much stronger grip so... I'm not kidding, a lot of ppl literally practice no religion whatsoever; probably got stamped out by the CCP. I think there might be a rather strong North/South divide in China: the North unfortunately has always been under stricter supervision by the party so...
Like they separate it very clearly. My grandparents' generation have old folk religion but ppl would call them "Mi Xin" so... my dad did burn the fake money things, but only during my grandparents' tomb cleanings or anything to do with the older generation. One of my grandparents is Buddhist, but she does make it quite clear. Otherwise most ppl I know literally have nothing remotely resembling religious in their apartments
