Mahjong (麻將) is a popular game in Chinese community. The game was invented two thousand years ago, and it’s often played as a gambling game these days.
Privately-run gambling businesses are illegal in Hong Kong, but there are legal mahjong schools for people to “learn to play” game. You can probably guess that most people who are learning in these schools are experts themselves.
There are not many licenses issued for mahjong school though; most of these schools can be found in Yau Tsim Mong district. Photo taken in Jordan area – a banner outside of a mahjong school showing the basic rules of the mahjong game, perhaps trying to make the place a bit more school like lol.
