Perhaps you should try some spelling variations:
wan hyoung » wang hyoung, man houng, min hyoung
chang min » zhang ming, chan ming, chang ann
chang mae » chang ha, changes made
tuan hua » tan hua, tuan vu, yuan hui
wong sau » wong sam, wong siu, wong shiu
gun hua » gui hua
yang xi » yang di, yang yi, yang jui

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wan hyoung ((gun hua) or (tuan hua)) ren ((((chang min) OR (chang mae))) or (yang xi)) wong sau ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan hyoung ((gun hua) OR (tuan hua)) ren ((((chang min) OR (chang mae))) OR (yang xi)) wong sau ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan hyoung ((gun hua) or (tuan hua)) ren ((((chang min) OR (chang mae))) or (yang xi)) wong sau ;*".
