Perhaps you should try some spelling variations:
gang yao » yang yao, wang yan, ganga ya
yang hua » wang hua, yang hui, yang jui
ying hua » ming hua, wang hua, ying zhu
rene yan » ren yan, rene ten, see yan
jiu wong » jiu cong, ji won, kie wong
wong sau » wong sam, wong siu, wong shiu
yan jiu » yang jie, yang jin, pang jiu

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: gang yao ((yang hua) OR (ying hua)) rene yan jiu wong sau ;~.
• Adding a wildcard symbol may retrieve word variants: gang yao ((yang hua) or (ying hua)) rene yan jiu wong sau ;*.
