Perhaps you should try some spelling variations:
chuan ming » chuan bang, yuan ming
yan huang » yang guang, yan guan, yan liang
chan ming » kian ming, chan eng, chan fong
huang yi » huang di, huang ying, huang bin
wan yan » wang yan, nan yan, wai yan
yi chen » jui chen
code 2 » code _, code a

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: wan yan huang yi chen ((chuan ming) OR (chan ming)) code 2 ;~.
• Adding a wildcard symbol may retrieve word variants: wan yan huang yi chen ((chuan ming) or (chan ming)) code 2 ;*.
