Perhaps you should try some spelling variations:
ping wang » ping pong, hong wang
wei sheng » kwei sheng, wei shang, lei sheng
shang hai » shang kai, dang hai, chang ha
nam ping » team ping, nam binh, nam dinh
wang wei » zhang wei, wang zhi
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: nam ping wang wei sheng ((((((yang jie) OR (yang di))) OR (yang jui))) OR (yang xi)) shang hai ;~.
• Adding a wildcard symbol may retrieve word variants: nam ping wang wei sheng ((((((yang jie) or (yang di))) or (yang jui))) or (yang xi)) shang hai ;*.
