Perhaps you should try some spelling variations:
ping wang » ping pong
hong wang » hong gang, hong kong, hong jong
yang zhu » ying zhu, fang zhou, gang zhou
zhu chen » zhe chen, zhi chen, zhiwu chen
yang jie » yang jin, yang jui, yang yi
wang hui » wang hua, wang zhi, wang wei
yang xi » yang yi, 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: ((ping wang) OR (hong wang)) yang zhu chen ((((yang jie) OR (yang xi))) OR (yang di)) wang hui ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ping wang) OR (hong wang)) yang zhu chen ((((yang jie) or (yang xi))) or (yang di)) wang hui ;~".
• Adding a wildcard symbol may retrieve word variants: ((ping wang) OR (hong wang)) yang zhu chen ((((yang jie) or (yang xi))) or (yang di)) wang hui ;*.
