Perhaps you should try some spelling variations:
tuan china » wuhan china, can china, taiwan china
lang yan » wang yan, wang yang, zhang yan
tan chia » than china, can china, dan china
yang jui » yang judy, yang di, yang xi
yan hua » tan hua, ya hua, wang hua
yan jiu » yang jie, yang jin, pang jiu
won sau » wong sau, wong sam, wong siu

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: lang yan ((yan hua) OR (((tan chia) OR (tuan china)))) gene ((yan jiu) OR (yang jui)) won sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan ((yan hua) or (((tan chia) OR (tuan china)))) gene ((yan jiu) or (yang jui)) won sau ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan ((yan hua) or (((tan chia) OR (tuan china)))) gene ((yan jiu) or (yang jui)) won sau ;*.
