I realize this is just anecdotal, but when I visited an Indian casino in SoCal, the roulette tables gamblers were all Chinese/Orientals. They covered the betting table for each spin of the wheel—hundreds of chips. It does seem that gambling appeals to them on a deep level.
Yes. My husband and I traveled through Hong Kong and Singapore many times and saw all the gambling casinos. The Chinese believe in LUCK and MONEY, so gambling is as embedded in their culture as is their writing.
They rely on 祝你好运.
