Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
gain yang » dan yang, daun yang, tan yang
zhang han » zhang fan, zhang yan, zhang hanmo
yan yuan » yan guan, fang yuan, nan yan
xi zhang » li zhang, xiao zhang, bin zhang
yan yun » yang yun, yan kun, yap yun
yang xi » yang di, yang yi, yang jui

You may be able to get more results by adjusting your search query.

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