Perhaps you should try some spelling variations:
wang liang » wang yang
wang wang » wang yang, wang yan, wang yong
yang jin » yang jie, yang jun, ying jin
wong sam » wong sau, wong lai, von sam
yan hua » tan hua, ya hua, wang hua
hua ren » hua chen
yang xi » yang di, yang yi, yang jui
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 wang) OR (wang liang)) yan hua ren ((yang jin) OR (yang xi)) ((wong sam) OR (kong sar)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang wang) or (wang liang)) yan hua ren ((yang jin) or (yang xi)) ((wong sam) OR (kong sar)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang wang) or (wang liang)) yan hua ren ((yang jin) or (yang xi)) ((wong sam) OR (kong sar)) ;*.
