Perhaps you should try some spelling variations:
wang frei » wang fei, wang lei
shang hai » shang kai, dang hai, chang ha
jin ying » li ying
wang wei » zhang wei, wang zhi
yang jie » yang jin, yang di, yang yi
yang jui » yang judy, yang di, yang yi
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 ying ((wang frei) OR (wang wei)) chen ((((yang jie) OR (yang xi))) OR (yang jui)) shang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "jin ying ((wang frei) OR (wang wei)) chen ((((yang jie) or (yang xi))) or (yang jui)) shang hai ;~".
• Adding a wildcard symbol may retrieve word variants: jin ying ((wang frei) OR (wang wei)) chen ((((yang jie) or (yang xi))) or (yang jui)) shang hai ;*.
