Perhaps you should try some spelling variations:
chang min » zhang ming, chang mae, chang ann
jeong shu » cong shu
chan ming » kian ming, chan eng, chan fong
wang qin » wang lin, wang qiao, wang jing
jeong su » jeong _, jeong mi, jeong 情
yuan li » yuan lin, guan li, yuan zi
yan li » yang li, gan li, tan li

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

• If you are trying to use Boolean operators, they must be ALL CAPS: wang qin ((yan li) OR (yuan li)) chen ((chang min) OR (chan ming)) ((jeong shu) OR (jeong su)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang qin ((yan li) OR (yuan li)) chen ((chang min) or (chan ming)) ((jeong shu) or (jeong su)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang qin ((yan li) OR (yuan li)) chen ((chang min) or (chan ming)) ((jeong shu) or (jeong su)) ;*.
