Perhaps you should try some spelling variations:
wang yang » wang liang, wang yanling
yang chen » kang chen, yung chen, chang chen
chen hua » chen chuan, chen shula, chen hao
dan yang » daun yang, tan yang, yang yang
tan yong » tan hong, tan kong, tan yang
li dang » le dang, li gang, li wang
hai » hadi, haji, hari

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