Perhaps you should try some spelling variations:
chan ming » kian ming, chan eng, chan kang
chan fong » chew fong, chan eng, chan kang
jeong shu » jeong su, cong shu
li sheng » lei sheng, li fasheng, l.t sheng
wan yan » wai yan, wang yang, qian yan
nan yan » nan ya, qian yan, dan yang
yuan li » yuan lin, guan li, yuan zi

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: ((((wan yan) OR (wang yan))) OR (nan yan)) yuan li sheng ((chan ming) OR (chan fong)) jeong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wan yan) or (wang yan))) or (nan yan)) yuan li sheng ((chan ming) OR (chan fong)) jeong shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((((wan yan) or (wang yan))) or (nan yan)) yuan li sheng ((chan ming) OR (chan fong)) jeong shu ;*.
