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 xi
dong bin » dong sin, dong di, dann bin
wai yan » wang yan, wei yang
yan yan » yan yuan, nan yan, yang yang
yang yi » yang xi, 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: wai yan yan guan rene ((((yang jie) OR (yang yi))) OR (yang di)) ((wong shiu) OR (dong bin)) ;~.
• Adding a wildcard symbol may retrieve word variants: wai yan yan guan rene ((((yang jie) or (yang yi))) or (yang di)) ((wong shiu) or (dong bin)) ;*.
