Perhaps you should try some spelling variations:
dong wang » hong wang, dong hoang, dong jung
dong yang » dong hoang, wang yang, yang yang
hua rene » hua ren, juan rene
yang jin » yang jun, ying jin, shang jin
yang jie » yang di, yang xi, yang yi
yang jui » yang judy, yang di, yang xi
wong sam » wong sau, wong lai, kong sar

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 ((dong wang) OR (dong yang)) hua rene ((((yang jin) OR (yang jie))) OR (yang jui)) wong sam ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((dong wang) OR (dong yang)) hua rene ((((yang jin) or (yang jie))) or (yang jui)) wong sam ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((dong wang) OR (dong yang)) hua rene ((((yang jin) or (yang jie))) or (yang jui)) wong sam ;*.
