Perhaps you should try some spelling variations:
chen chan » chen chuan, cheung chan, chen chung
chan ming » kian ming, chan eng, chan fong
jeong su » jeong _, jeong 情
jeong mi » jeong _, jeong 情, jong min
nan yan » nan ya, wang yan, qian yan
rong su » rong yu, cong sun, yong suk
yan li » yang li, yuan 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: nan yan ((yan li) OR (gan li)) chen chan ming ((((jeong su) OR (rong su))) OR (jeong mi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nan yan ((yan li) or (gan li)) chen chan ming ((((jeong su) OR (rong su))) or (jeong mi)) ;~".
• Adding a wildcard symbol may retrieve word variants: nan yan ((yan li) or (gan li)) chen chan ming ((((jeong su) OR (rong su))) or (jeong mi)) ;*.
