Perhaps you should try some spelling variations:
yong yoon » wong yoon, yong khoon
dong yang » dong hoang, wang yang, yang yang
yong yan » yang yang, ying yang, wang yan
hua rene » hua ren, juan rene
yang jun » pang jun, yang jin, yang judy
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.

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((((yong yan) OR (yong yoon))) or (dong yang)) hua rene ((yang jun) or (yang jui)) wong sam ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((((yong yan) OR (yong yoon))) OR (dong yang)) hua rene ((yang jun) OR (yang jui)) wong sam ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yong yan) OR (yong yoon))) or (dong yang)) hua rene ((yang jun) or (yang jui)) wong sam ;".
• Adding a wildcard symbol may retrieve word variants: wang ((((yong yan) OR (yong yoon))) or (dong yang)) hua rene ((yang jun) or (yang jui)) wong sam ;*.
