Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
wang yong » wang yang, wang hyoung, wang yan
yong yan » yang yang, dong yang, ying yang
yan guan » gan guan, yan yuan, yang guang
tan yang » tan ying, tan yong, tao yang
dan yang » daun yang, wang yang, yang yang
xi shang » xia shang, xi zhang, wei shang

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