Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
yin hang » yin fang, yin yang, ying chang
yang jin » yang jie, yang jun, ying jin
yang jui » yang judy, yang di, yang xi
tan yin » tan ying, tan xin, tan yi
hang yu » hong yu, sang yu, chang you
yu chen » yu cheng, yi chen, yulu chen
yang yi » yang di, yang xi

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 yin hang yu chen ((((yang yi) OR (yang jin))) OR (yang jui)) shang hai ;~.
• Adding a wildcard symbol may retrieve word variants: tan yin hang yu chen ((((yang yi) or (yang jin))) or (yang jui)) shang hai ;*.
