Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
dean hua » dean a, tuan hua
ying jin » yang jin, jing ji, yang jie
wong sau » wong sam, wong siu, wong shiu
tan hua » tuan hua, wang hua, tan chia
yan jiu » yang jie, yang jin, pang jiu
sar » sara, star, saur

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 yang ((dean hua) OR (tan hua)) gain ((yan jiu) OR (ying jin)) ((wong sau) OR (kong sar)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang ((dean hua) OR (tan hua)) gain ((yan jiu) or (ying jin)) ((wong sau) or (kong sar)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang ((dean hua) OR (tan hua)) gain ((yan jiu) or (ying jin)) ((wong sau) or (kong sar)) ;*.
