Perhaps you should try some spelling variations:
yuan gain » run gain, yuan lin
yuan kai » yuan kang, yuan fei, tan kai
kang hay » eang hay, kang han, dang hai
yan yan » yan yuan, nan yan, yang yang
yang wu » yang du, yang jui, yang jun
yang mu » yang du, yang muxi, yang jui
wang » wing, wan, lang

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