Perhaps you should try some spelling variations:
yuan wang » yan wang, yuan kang, yuan chang
yuhan hua » yuan hui, yuhuan huang
chan eng » chan fong, chan kang, chan ming
yang jui » yang judy, yang di, yang xi
tuan hua » tan hua, tuan vu, yuan hui
wang yue » wong yue, wang hua, wang yan
han min » han men, kan min, chan ming

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: yuan wang ((yuhan hua) OR (tuan hua)) ren ((yang jui) OR (((han min) OR (chan eng)))) wang yue ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yuan wang ((yuhan hua) OR (tuan hua)) ren ((yang jui) or (((han min) or (chan eng)))) wang yue ;~".
• Adding a wildcard symbol may retrieve word variants: yuan wang ((yuhan hua) OR (tuan hua)) ren ((yang jui) or (((han min) or (chan eng)))) wang yue ;*.
