Only other thing I see is that you said he was born in china, however there is no china anymore. its been 450 years since the surface of the earth was civilized. 

Maybe something like "Former Eastern Asia"? 

other than that, and a very short backstory (you could definitely flesh it out, take a day to just brainstorm stuff for your character) Id say hes okay.
