Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
tan yong » tan hong, tan kong, tan yang
sang yun » sang yu, song yun, tang yun
yun chen » yung chen, yu chen, yuan cheng
yang jin » yang jie, yang jun, ying jin
yang xi » yang di, yang jui
yang yi » yang di, 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: ((tan yong) OR (li ying)) sang yun chen ((((yang xi) OR (yang jin))) OR (yang yi)) shang hai ;~.
• Adding a wildcard symbol may retrieve word variants: ((tan yong) or (li ying)) sang yun chen ((((yang xi) or (yang jin))) or (yang yi)) shang hai ;*.
