Perhaps you should try some spelling variations:
jeong shu » jeong su, cong shu
chan ming » kian ming, chan fong, chan kang
yan guan » gan guan, yan yuan, yang guang
chan eng » chan fong, chan kang, han en
qian yan » qian jun, qian yi
yi chen » jui chen
nan yan » nan ya, wang yan, dan yang

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: lang ((yan guan) OR (((nan yan) OR (qian yan)))) yi chen ((chan ming) OR (chan eng)) jeong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang ((yan guan) or (((nan yan) or (qian yan)))) yi chen ((chan ming) OR (chan eng)) jeong shu ;~".
• Adding a wildcard symbol may retrieve word variants: lang ((yan guan) or (((nan yan) or (qian yan)))) yi chen ((chan ming) OR (chan eng)) jeong shu ;*.
