Perhaps you should try some spelling variations:
chang chuan » chung chuan, chen chuan, chang ch'un
chuan cheng » huang cheng, yuan cheng
shang hai » shang kai, dang hai, chang ha
yi chang » ii chang, ying chang, jin chang
yang jun » yang jui, pang jun, yang jin
tang yi » tang li, tan yi, jiang yi
yang yi » yang jui
yang xi » yang jui

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: tang yi chang chuan cheng ((((((yang di) OR (yang jun))) OR (yang yi))) OR (yang xi)) shang hai ;~.
• Adding a wildcard symbol may retrieve word variants: tang yi chang chuan cheng ((((((yang di) or (yang jun))) or (yang yi))) or (yang xi)) shang hai ;*.
