Perhaps you should try some spelling variations:
cong shu » cong shi, nong shu, tong shu
yu ling » yu liang, yu ting, yu lin
ji cong » ji song, li cong, xi cong
fu ming » yu ming, fu ying, wu ming
ji yong » jim yong, ji young, li yong
chen x » chen xi, chen _, chen 9
chen a » chen _
i she » vi she, xi she, i shew
bao » bajo

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: (( yu ling ((chen x) OR (chen a)) she ji cong shu ) OR ( fu ming ((chen x) OR (chen a))i she ji yong bao )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( yu ling ((chen x) OR (chen a)) she ji cong shu ) or ( fu ming ((chen x) OR (chen a))i she ji yong bao ))".
• Adding a wildcard symbol may retrieve word variants: (( yu ling ((chen x) OR (chen a)) she ji cong shu ) or ( fu ming ((chen x) OR (chen a))i she ji yong bao ))*.
