Perhaps you should try some spelling variations:
tuan juan » huang juan, san juan
tuan hua » tan hua, tuan vu, yuan hui
yang jin » yang jun, ying jin, shang jin
yang jie » yang di, yang xi, yang yi
yang jui » yang judy, yang di, yang xi
wong siu » wong shiu, kong siu, wong sau
wan yan » wang yan, nan yan, wai yan

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: wan yan ((tuan juan) OR (tuan hua)) rene ((((yang jin) OR (yang jie))) OR (yang jui)) wong siu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan ((tuan juan) OR (tuan hua)) rene ((((yang jin) or (yang jie))) or (yang jui)) wong siu ;~".
• Adding a wildcard symbol may retrieve word variants: wan yan ((tuan juan) OR (tuan hua)) rene ((((yang jin) or (yang jie))) or (yang jui)) wong siu ;*.
