Perhaps you should try some spelling variations:
wang liang » wang yang
liang dan » liang tan, king dan, liang sun
kong saur » kong sar, kong siu, kong your
pang jiu » pang jun, yang jie, pan ji
yang jin » yang jie, yang jun, ying jin
wong sam » wong sau, wong lai, kong sar
yan jiu » yang jie
a rein » a reine, a reit, a region
dan a » dan la, can a, das a

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: wang liang dan a rein ((((yan jiu) OR (pang jiu))) OR (yang jin)) ((kong saur) OR (wong sam)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang liang dan a rein ((((yan jiu) or (pang jiu))) or (yang jin)) ((kong saur) or (wong sam)) ;*.
