Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
ping john » king john, kong john, wong john
kong star » kong sar
yang hua » wang hua, yang hui, yang jui
ying hua » ming hua, wang hua, ying zhu
ren ping » chen ping, yuen ping, fun ping
von sam » von sa, von sap, von sach

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 yang ((yang hua) OR (ying hua)) ren ping john ((((von sam) OR (von scham))) OR (kong star)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang ((yang hua) OR (ying hua)) ren ping john ((((von sam) or (von scham))) or (kong star)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang ((yang hua) OR (ying hua)) ren ping john ((((von sam) or (von scham))) or (kong star)) ;*.
