Where is English language change button?

I will start by saying I really like this game, but you better wish you are playing the mainland version, cuz this international one is a joke. Game constantly makes “tiny” bug fix updates that destroy player’s hero talents and equipment to be made. The company responsible for O&M does nothing but playing dumb every time. Overall this international version is not worthy of your time and money! Edit Apr 2: O&M team’s response to this recent incident is “please be careful not to play this game in such a high-risk fashion”. Turns out playing this game normally is highly risky! What a joke!

I wish it has more freedom of development instead of pre-set story lines. If you don’t know the hidden story lines (look up for the detailed walkthroughs), then time is being wasted. But then if you play it with the walkthroughs then it is not what I am looking for. I wish I can develop my characters my own way and still can grow and compete with others.

please give me english version of the game sob ,_, I understand Chinese, but I'm more comfortable with english.
