Mahjong, weiqi and XQ seem to be the big ones in China. Mahjong is aesthetically appealing but it is more or less just a card game.
Mahjong=A card game with money
Cards are very very popular too, more as xiangqi I think.
Mahjong, cards and xiangqi: in all cities I went you can see players outside (and in dedicated rooms). Like dance at night, a big part of the population practice that every day.
Weiqi is far less common.
As a continuation of the discussion, originally at Forum games for 2021? - #7 by bugcat, of Mahjong as a forum game, here are the relevant Unicode characters from Mahjong Tiles (Unicode block) - Wikipedia

π« tile back
Instead of , Iβd consider using δΈ.
A less heavy symbol, like ε, could also replace the tile back if desired.
It was developed in the 19th century and mostly a gambling game. Not that old.
