Perhaps you should try some spelling variations:
qian yan » qian jun, qian yi
hua rene » hua ren, juan rene
yang jin » yang jie, yang jun, ying jin
jin wong » jin song, john wong, jin ying
wong sam » wong sau, wong lai, kong sar
nan yan » nan ya, dan yang, nana yaa
yan hua » tan hua, ya hua, wang hua

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: ((((qian yan) OR (nan yan))) OR (wang yan)) yan hua rene yang jin wong sam ;~.
• Adding a wildcard symbol may retrieve word variants: ((((qian yan) or (nan yan))) or (wang yan)) yan hua rene yang jin wong sam ;*.
