Perhaps you should try some spelling variations:
wang yong » wang hyoung, wang yan, wang shiyong
wang yang » wang yan, wang liang, wang yanling
yuan kang » yuan wang, yuan chang, chan kang
yuan kai » yuan fei, tan kai, yuan hui
tan kah » tan ah, tan kai
yang wu » yang du, yang mu, yang jui
wu dang » wu kang, duc dang, wu guang
hai » hadi, haji, hari

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) OR (wang yang)) yan ((((yuan kai) OR (yuan kang))) OR (tan kah)) yang wu dang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yong) OR (wang yang)) yan ((((yuan kai) or (yuan kang))) or (tan kah)) yang wu dang hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yong) OR (wang yang)) yan ((((yuan kai) or (yuan kang))) or (tan kah)) yang wu dang hai ;*.
