The best place to play poker that I know of and have found is the Hong Kong Poker House (HKPH). Its in central, on hollywood road, they play cash games there and there is a league i believe, its called the Hong Kong Poker League. The poker house is totally legit because it doesnt take a rake like a casino would. They have a website, its: hkph dot com dot hk and the league is found at: hkpokerleague dot com

There is also a poker tv website which i found that has videos on there that i was not able to find on youtube. Its called pokertvasia, the website is at: pokertvasia dot com
There is also another website called "Chinese Poker Player Association" (CPPA) which can be found at: cppapoker dot com

CPPA has some other cool media on there and forums, etc, so check it all out!

Hope that helps!
