Perhaps you should try some spelling variations:
chin chang » china chang, chain change, china zhang
chih hang » shih huang, chih yung
wang nan » wang yan, wang ban, wang dan
wang lin » wang li, wang qin, yang lin
yang jin » yang jie, yang jun, ying jin
tong hui » wang hui
yang li » yang lin, yang di, yang xi

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