Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
trinh cua » tinh cua, trinh luat, trinh quan
cua nhung » va nhung
cong dan » cong san, cong tan, cong dong
than ban » thanh ban, toan ban, nhuan ban
than man » than ma, thanh san, tran manh
va kinh » va tinh, qua kinh

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: hoi va kinh - hanh trinh cua nhung ((cong dan) OR (huong dan)) ((than ban) OR (than man))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoi va kinh - hanh trinh cua nhung ((cong dan) OR (huong dan)) ((than ban) or (than man))~".
• Adding a wildcard symbol may retrieve word variants: hoi va kinh - hanh trinh cua nhung ((cong dan) OR (huong dan)) ((than ban) or (than man))*.
