Perhaps you should try some spelling variations:
chung chuan » chen chuan
chuan cheng » huang cheng, yuan cheng
yin chung » hin cheung, lin chun, yin hang
shang hai » shang kai, dang hai, chang ha
yang jui » yang judy, yang yi
yang jie » yang jin, yang yi, yang jun
ran yin » ran ying, fan ying, tan ying
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: ran yin chung chuan cheng ((((yang jui) OR (yang jie))) OR (((yang xi) OR (yang di)))) shang hai ;~.
• Adding a wildcard symbol may retrieve word variants: ran yin chung chuan cheng ((((yang jui) or (yang jie))) or (((yang xi) or (yang di)))) shang hai ;*.
