Perhaps you should try some spelling variations:
chin chang » china chang, chain change, china zhang
chang yun » chong yun, chang hsun, chae yun
shang hai » shang kai, dang hai, chang ha
tan chin » tan chia, tuan china, than china
yun chen » yung chen, yu chen, yuan cheng
yang jie » yang jin, yang jui, yang jun
yang yi » yang jui
yang xi » yang jui

You may be able to get more results by adjusting your search query.
