Perhaps you should try some spelling variations:
yang jun » pang jun, yang jin, yang judy
yang jie » yang jin, yang di, yang xi
yang jui » yang judy, yang di, yang xi
wong sam » wong sau, kong sar, von sam
yan yan » yan yuan, nan yan, yang yang
yan hua » tan hua, ya hua, wang hua
hua ren » hua chen
wang » wing, wan, lang
lai » laid

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