Perhaps you should try some spelling variations:
wang ying » wang yang, wang yong, wang jing
ying yang » yang yang, yin yang, ying chang
yang phua » wang hua, yang hui
lye chang » lee chang, yeo chang, yi chang
chang min » zhang ming, chang mae, chan ming
wong sam » wong lai, kong sar, von sam
wong sau » wong siu, wong shiu, wong lai
won sau » wong siu

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang ying yang phua lye chang min ((((won sau) OR (wong sam))) or (wong sau)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ying yang phua lye chang min ((((won sau) OR (wong sam))) OR (wong sau)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ying yang phua lye chang min ((((won sau) OR (wong sam))) or (wong sau)) ;*".
