Perhaps you should try some spelling variations:
yuan kang » yuan wang, yuan chang, chan kang
yuan kai » yuan fei, tan kai, yuan hui
yan yan » yan yuan, nan yan, yang yang
tan kah » tan ah, tan kai
yang wu » yang du, yang mu, yang jui
wu dang » wu kang, duc dang, wu guang
wang » wing, wan, lang
hai » hadi, haji, hari

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 yan yan ((((yuan kai) OR (yuan kang))) OR (tan kah)) yang wu dang hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan yan ((((yuan kai) OR (yuan kang))) OR (tan kah)) yang wu dang hai ;*.
