Perhaps you should try some spelling variations:
yan zhang » yuan chang, bin zhang, han chang
zhang l.t » zhang lei, zhang li, zhang lin
l.t sheng » lei sheng
shang hai » shang kai, dang hai, chang ha
yang jun » pang jun, yang jin, yang judy
yang jui » yang judy, yang xi
yang yi » yang xi
wang » wing, wan, lang

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: wang yan zhang l.t sheng ((((((yang di) OR (yang yi))) OR (yang jun))) OR (yang jui)) shang hai ;~.
• Adding a wildcard symbol may retrieve word variants: wang yan zhang l.t sheng ((((((yang di) or (yang yi))) or (yang jun))) or (yang jui)) shang hai ;*.
