I think the TS is biased against the Chinese.
When I am in San Jose, California USA, I went to small casino & card house in that city. I saw most professional gamblers are Americans (red hair) and Black guys. The hard-core gamblers there are the Vietnameses lose every single dollars they have until commit suicide.
In US, there is also WL working inside pubs while ang mohs patronise them for sexual services.
No different from Asian countries.
So please do not have impression that Chinese like like to visit prostitutes and gamble. The Amercians (Westerners) and Japaneses they too like to visit prostitutes and gamble even more hard-core than the Chinese in Asia
