30.28 million people and 371 million RMB... It's difficult to catch these number are large or not, so I'll let you know the whole scale size of Chinese mobile game market.
The whole number of Chinese mobile game users were 162 million people as of Q4,2011.
And whole revenue of Chinese mobile game market was 1099 million RMB(about 174.65 million dollars).
So it can be said compared with Chinese mobile game market, its mobile online game users were about one fifth scale, and its revenue was one third.
Looking this comparison, you might feel it is too small, but I think its market is still in early stage now. And improving connection speed, it will be dramatically increasing.
