Perhaps you should try some spelling variations:
ping wang » ping pong, hong wang
wang fang » wang yang, weng fang, wang liang
fang zhou » gang zhou, fang zhen
zhou chen » zhu chen, zhiwu chen, zhe chen
yang jun » yang jui, pang jun, yang jin
tong hui » wang hui
yang xi » yang yi, yang jui

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