Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
dang hadi » dang hai
yan yuan » yan guan, fang yuan, yan clan
fan guon » gan guan, yan guan
kai yang » kai fang, yao yang, dan yang
yang jin » yang jie, yang jun, ying jin
jin dang » jin kang, jin chang, jing fang
nan yan » nan ya, wang yan, qian yan

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 yuan) OR (nan yan))) OR (fan guon)) kai yang jin dang hadi ;~.
• Adding a wildcard symbol may retrieve word variants: wang yong ((((yan yuan) or (nan yan))) or (fan guon)) kai yang jin dang hadi ;*.
