Perhaps you should try some spelling variations:
ying zhang » ying chang, bin zhang, yan zhang
zhang wei » zhen wei
shang hai » shang kai, dang hai, chang ha
wei chen » wei shen, frei chen, jui chen
yang jie » yang jin, yang yi, yang jun
yang jui » yang judy, yang yi
yang xi » 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: li ying zhang wei chen ((yang jie) OR (((((yang jui) OR (yang xi))) OR (yang di)))) shang hai ;~.
• Adding a wildcard symbol may retrieve word variants: li ying zhang wei chen ((yang jie) or (((((yang jui) or (yang xi))) or (yang di)))) shang hai ;*.
