Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang shiyong
hua irene » hua ren
yang jin » yang jie, yang jun, ying jin
long shu » cong shu, tong shui, long du
wong sau » wong sam, wong siu, wong shiu
yan hua » tan hua, ya hua, wang hua
yan jiu » yang jie, 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: ((wang yong) OR (wang yan)) yan hua irene ((yan jiu) OR (yang jin)) ((long shu) OR (wong sau)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yong) OR (wang yan)) yan hua irene ((yan jiu) or (yang jin)) ((long shu) or (wong sau)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yong) OR (wang yan)) yan hua irene ((yan jiu) or (yang jin)) ((long shu) or (wong sau)) ;*.
