Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
yang wang » yang yang, yan wang, yang guang
wang hai » dang hai, wang hui, shang hai
yang jin » yang jie, yang jun, ying jin
wong sam » wong sau, wong lai, von sam
yang yi » yang xi, yang jui
sar » sara, star, saur

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wang yang wang hai ren ((((yang jin) or (yang yi))) or (yang di)) ((wong sam) OR (kong sar)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang wang hai ren ((((yang jin) OR (yang yi))) OR (yang di)) ((wong sam) OR (kong sar)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang wang hai ren ((((yang jin) or (yang yi))) or (yang di)) ((wong sam) OR (kong sar)) ;*".
