Perhaps you should try some spelling variations:
dang wang » wang yang, dang anh, dang hung
wang yong » wang yang, wang hyoung, wang yan
chang min » zhang ming, chang mae, chan ming
yong hua » dong hua, ying hua, wang hua
yang lin » yang jin, wang lin, yang li
wong yue » wang yue, hong yu
yang xi » yang di, yang yi, yang jui

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