Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
hua zhang » hua zhong, hao zhang, hua jiang
zhang zhi » zhong zhi, wang zhi, zhang wei
yin fang » yin hang, yin yang, chin fang
fang hua » wang hua, fang yuan, wang hui
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.
