Perhaps you should try some spelling variations:
ping wang » ping pong, hong wang
shang kai » shang hai
wang wei » zhang wei, wang zhi
wei chen » wei shen, frei chen, jui chen
yang jie » yang jin, yang di, yang jui
li ping » li ying, li bing, li ning
yang yi » yang di, yang jui
yang xi » yang di, yang jui

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 ping wang wei chen ((yang jie) OR (((yang yi) OR (yang xi)))) shang kai ;~.
• Adding a wildcard symbol may retrieve word variants: li ping wang wei chen ((yang jie) or (((yang yi) or (yang xi)))) shang kai ;*.
