Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
yi chang » ii chang, ying chang, jin chang
chang yi » chong yi, zhang yi, chang gui
yang jun » yang jui, pang jun, yang judy
yang jin » yang jie, ying jin, shang jin
yi chen » jui chen
yang yi » yang di, yang jui
yang xi » yang di, yang jui
tan yi » tang yi, tan li, tan ying

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 yi chang yi chen ((((((yang jun) OR (yang jin))) OR (yang yi))) OR (yang xi)) shang hai ;~.
• Adding a wildcard symbol may retrieve word variants: tan yi chang yi chen ((((((yang jun) or (yang jin))) or (yang yi))) or (yang xi)) shang hai ;*.
