Perhaps you should try some spelling variations:
guan rene » juan rene, glas rene
wong shiu » wong siu, cong shu, song shin
yan guan » gan guan, yan yuan, yang guang
yang jie » yang jin, yang jui, yang yi
dong bin » dong sin, dong di, dann bin
wan yan » wang yan, nan yan, wai yan
yan yan » yan yuan, nan yan, yang yang
yang xi » yang yi, yang jui

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: wan yan yan guan rene ((((yang jie) OR (yang xi))) OR (yang di)) ((wong shiu) OR (dong bin)) ;~.
• Adding a wildcard symbol may retrieve word variants: wan yan yan guan rene ((((yang jie) or (yang xi))) or (yang di)) ((wong shiu) or (dong bin)) ;*.
