Perhaps you should try some spelling variations:
chuan chen » chang chen, hua chen
hai chuan » say chuan, ka chuan, tai chun
chan ming » kian ming, chan fong, chan kang
chan eng » chan fong, chan kang, han en
yan hai » dang hai
han min » han men, kan min, chang min
wang » wing, wan, lang

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

• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan hai chuan chen ((((chan eng) OR (han min))) OR (chan ming)) cong shu ;~.
• Adding a wildcard symbol may retrieve word variants: wang yan hai chuan chen ((((chan eng) or (han min))) or (chan ming)) cong shu ;*.
