Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
yang yun » yang jun, tang yun, yang yue
dan yang » daun yang, tan yang, wang yang
xi shang » xia shang, xi zhang, wei shang
yan yun » yan yuan, yan kun, yap yun
yang xi » yang di, yang yi, yang jui
wang » wing, wan, lang

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: wang yan ((yan yun) OR (yang yun)) dan yang xi shang hai ;~.
• Adding a wildcard symbol may retrieve word variants: wang yan ((yan yun) or (yang yun)) dan yang xi shang hai ;*.
