Perhaps you should try some spelling variations:
chung chuan » chen chuan
chuan zhang » chuan bang, xiulan zhang
yang liang » wang liang, yan liang, yang yang
zhang wei » zhen wei
yang jui » yang judy, yang yi
yi chung » yi chang, lai chung, wai chung
wan yan » wang yan, nan yan, wai yan
yang xi » yang yi

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 ((((((yang liang) OR (yang xi))) OR (yang jui))) OR (yang di)) yi chung chuan zhang wei ;~.
• Adding a wildcard symbol may retrieve word variants: wan yan ((((((yang liang) or (yang xi))) or (yang jui))) or (yang di)) yi chung chuan zhang wei ;*.
