Perhaps you should try some spelling variations:
guan rene » juan rene, glas rene
wong shiu » wong siu, cong shu, song shin
dong sind » dong sin, dong bin, dong ping
lang yan » wang yan, wang yang, zhang yan
gui guan » gan guan, gui hua, tuo guan
yang jie » yang jin, yang jui, yang xi
yan gui » yan guan, zhan gui
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: lang yan gui guan rene ((((yang jie) OR (yang yi))) OR (yang di)) ((wong shiu) OR (dong sind)) ;~.
• Adding a wildcard symbol may retrieve word variants: lang yan gui guan rene ((((yang jie) or (yang yi))) or (yang di)) ((wong shiu) or (dong sind)) ;*.
