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 chen » wei shen, frei chen, jui chen
yang jui » yang judy, yang yi
nan yan » nan ya, wang yan, qian yan
yang xi » yang yi

You may be able to get more results by adjusting your search query.

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