Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
zhang han » zhang fan, zhang yan, zhang hanmo
yau yung » au yong, yap yun
yan guan » gan guan, yan yuan, yang guang
tan yang » dan yang, tan ying, tan yong
yi zhang » li zhang, xi zhang, yi chang
yan kun » yan yuan
yang yi » yang di, yang xi, 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: wang yong ((((yan kun) OR (yau yung))) OR (yan guan)) tan yang yi zhang han ;~.
• Adding a wildcard symbol may retrieve word variants: wang yong ((((yan kun) or (yau yung))) or (yan guan)) tan yang yi zhang han ;*.
