Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
zhong tai » hong tan, hong hai, zhong zhi
yang yun » yang jun, tang yun, yang yue
tan yang » dan yang, tan ying, tan yong
wang li » wang lei, wang lin, tang li
li yang » liu yang, li ying, li gang
yun tan » yun jang

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 li yang yun tan yang di ((shang hai) OR (zhong tai)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang li yang yun tan yang di ((shang hai) or (zhong tai)) ;*.
