Not Chinese, used to live in China, still living in Asia.
All the online bookies you love can be accessed from China. Sports betting is officially illegal except in Macau so a lot of in-person betting takes place in the shadows. But really, no one gives a fuck unless you make a lot of noise. In fact, a lot of things work that way in China.
What it's like to live in China? That's kind of like asking what it's like to live in the USA. Huge place, plenty of variety. Generally speaking, Asia is a lot safer than the West due to traditional values/education, strict immigration policies, and no tolerance policies on drug possession. You can walk around many of the inner cities in the middle of the night and feel safe.
