Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
yang wang » yang yang, yan wang, yang guang
wong shiu » wong siu, cong shu, song shin
yang jie » yang jin, yang di, yang jui
wong sam » wong sau, wong lai, von sam
hua ren » hua chen
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 wang hua ren ((yang jie) OR (yang judy)) ((wong shiu) OR (((wong sam) OR (kong sar)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang wang hua ren ((yang jie) or (yang judy)) ((wong shiu) or (((wong sam) OR (kong sar)))) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang wang hua ren ((yang jie) or (yang judy)) ((wong shiu) or (((wong sam) OR (kong sar)))) ;*.
