Perhaps you should try some spelling variations:
yan shang » yan zhang, yuan chang, gao shang
shang hai » shang kai, dang hai, chang ha
yang jin » yang jie, ying jin, shang jin
yang jun » yang jui, pang jun, yang judy
wong sam » wong sau, wong lai, kong sar
wai yan » wang yan, wei yang
yang xi » yang yi, 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 shang hai ren ((((yang jin) OR (yang jun))) OR (((yang xi) OR (yang di)))) wong sam ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wai yan shang hai ren ((((yang jin) OR (yang jun))) or (((yang xi) or (yang di)))) wong sam ;~".
• Adding a wildcard symbol may retrieve word variants: wai yan shang hai ren ((((yang jin) OR (yang jun))) or (((yang xi) or (yang di)))) wong sam ;*.
