Perhaps you should try some spelling variations:
yan zhang » yuan chang, bin zhang, han chang
zhang wei » zhen wei
shang hai » shang kai, dang hai, chang ha
wei shen » kwei sheng, enwei shen, wei shang
yang jie » yang jin, yang xi, yang jun
yang jui » yang judy, yang xi
jin yan » jin ying, qian yan, jiao yan
yang yi » yang xi

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 zhang wei shen ((yang jie) OR (((((yang yi) OR (yang jui))) OR (yang di)))) shang hai ;~.
• Adding a wildcard symbol may retrieve word variants: jin yan zhang wei shen ((yang jie) or (((((yang yi) or (yang jui))) or (yang di)))) shang hai ;*.
