Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
wei chen » wei shen, frei chen, jui chen
yang wei » wang wei, fang wei, zhang wei
yang jui » yang judy, yang di, yang xi
yang jin » yang jie, yang jun, ying jin
wann yu » wang yue
yang yi » yang di, yang xi
wan yu » wang yue, whan yun

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: ((wan yu) OR (wann yu)) yang wei chen ((((yang jui) OR (yang jin))) OR (yang yi)) shang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan yu) OR (wann yu)) yang wei chen ((((yang jui) or (yang jin))) or (yang yi)) shang hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((wan yu) OR (wann yu)) yang wei chen ((((yang jui) or (yang jin))) or (yang yi)) shang hai ;*.
