Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
wang ban » wang yan, wang dan, bang bang
wong sam » wong sau, wong lai, kong sar
kong siu » kong eiu, wong siu, dong sin
chia wen » china won, ching wen, asia wen
yan jiu » yang jie, yang jin, pang jiu
yan jie » yang jie, yang jin, huan jie

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: qian ((wang ban) OR (wang yang)) chia wen ((yan jie) OR (yan jiu)) ((wong sam) OR (kong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "qian ((wang ban) or (wang yang)) chia wen ((yan jie) OR (yan jiu)) ((wong sam) or (kong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: qian ((wang ban) or (wang yang)) chia wen ((yan jie) OR (yan jiu)) ((wong sam) or (kong siu)) ;*.
