Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
gain yang » dan yang, daun yang, tan yang
yan guan » gan guan, yan yuan, yang guang
gang hai » dang hai, shang hai, eang hay
yan yun » yan yuan, yang yun, yap yun
yan kun » yan yuan
yang xi » yang di, yang yi, yang jui
xi gang » ii gang, i gang, li gang

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 yong ((yan yun) OR (((yan kun) OR (yan guan)))) gain yang xi gang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong ((yan yun) or (((yan kun) OR (yan guan)))) gain yang xi gang hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong ((yan yun) or (((yan kun) OR (yan guan)))) gain yang xi gang hai ;*.
