麻將據說是中國國粹.

台灣麻將打十六張牌. 和中國麻將不太一樣.

Oh, this is interesting topic. Does anyone tell me how much is mahjong popular? Like generation, frequency, where you play etc. Because I've seen old people doing mahjong in a park in China many times, but not young or middle age people. 

majiang, no doubt

you are right  majiang is the most popular gambling method 

I'm not 100% sure, but I have been to Macau, and the money flowing through there is way more than Vegas. It's pretty amazing actually the casions they have.
