Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
yan wang » yuan wang, yang yang, qian wang
wang wei » zhang wei, wang zhi
wei chen » wei shen, frei chen, jui chen
yang jun » pang jun, yang jin, yang judy
yang jui » yang judy, yang di, yang yi
jin yan » jin ying, qian yan, jiao yan
yang xi » yang di, yang yi

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