The Chinese version is full of "features" designed to force the player to spend money on gems (which can only be obtained by paying real money - there is a very limited amount of free gems in the game). Many plants can only be obtained through the lottery system.

The International version can be easily completed without paying a single cent. This is much more difficult to do in the Chinese version. You have to do a lot more grinding if you don't want to spend real money, and some levels are still very difficult to beat without spending gems.
