Perhaps you should try some spelling variations:
lang yan » wang yan, wang yang, zhang yan
tan chia » tuan china, than china, can china
yang jie » yang jin, yang di, yang yi
yang jui » yang judy, yang di, yang yi
yan hua » tan hua, ya hua, wang hua
yang xi » yang di, yang yi
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)) gene ((((yang jie) OR (yang xi))) 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)) gene ((((yang jie) OR (yang xi))) or (yang jui)) won sau ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan ((yan hua) or (tan chia)) gene ((((yang jie) OR (yang xi))) or (yang jui)) won sau ;*.
