Perhaps you should try some spelling variations:
chung chuan » chen chuan
chuan zhang » chuan bang, xiulan zhang
wang liang » wang yang
zhang wei » zhen wei
yang jie » yang jin, yang xi, yang yi
yang jui » yang judy, yang xi, yang yi
yi chung » yi chang, lai chung, wai chung
nan yan » nan ya, wang yan, qian 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: nan yan ((((((wang liang) OR (yang jie))) OR (yang jui))) OR (yang di)) yi chung chuan zhang wei ;~.
• Adding a wildcard symbol may retrieve word variants: nan yan ((((((wang liang) or (yang jie))) or (yang jui))) or (yang di)) yi chung chuan zhang wei ;*.
