Perhaps you should try some spelling variations:
chen hao » cheng han
yang jun » pang jun, yang jin, yang judy
yang jui » yang judy, yang di
wong sau » wong sam, wong siu, wong shiu
hao yan » yao yang, jiao yan, tao yang
yang xi » yang di
yang yi » yang di
yan a » can a, yan _, jan a

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: chen hao yan a gender ((yang jun) OR (((((yang xi) OR (yang jui))) OR (yang yi)))) wong sau ;~.
• Adding a wildcard symbol may retrieve word variants: chen hao yan a gender ((yang jun) or (((((yang xi) or (yang jui))) or (yang yi)))) wong sau ;*.
