Perhaps you should try some spelling variations:
chang chuan » chung chuan, chen chuan, chang ch'un
joon chang » hoong chang, boon chong, jin chang
chuan chen » chang chen, hua chen
yang july » yang judy, yang jun
can joon » can join, can job, ha joon
yang jui » yang judy, yang yi
wang hai » dang hai, wang hui, shang hai
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: can joon chang chuan chen ((((yang jui) OR (yang xi))) OR (((yang di) OR (yang july)))) wang hai ;~.
• Adding a wildcard symbol may retrieve word variants: can joon chang chuan chen ((((yang jui) or (yang xi))) or (((yang di) or (yang july)))) wang hai ;*.
