Perhaps you should try some spelling variations:
qian yan » qian jun, qian yi
hua rene » hua ren, juan rene
yang jie » yang jin, yang di, yang jui
wong sau » wong sam, wong siu, wong shiu
yan yan » yan yuan, nan yan, yang yang
von sam » von sa, von sap, von scham
nan ya » nan yan, nana yaa

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: wing ((yan yan) OR (((nan ya) OR (qian yan)))) hua rene yang jie ((von sam) OR (wong sau)) ;~.
• Adding a wildcard symbol may retrieve word variants: wing ((yan yan) or (((nan ya) or (qian yan)))) hua rene yang jie ((von sam) or (wong sau)) ;*.
