Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu sach » chinh sach, chiet tach, chieu sang
doi chieu » doc hieu, doi chi, ho chieu
cua nhung » va nhung
cong dan » cong san, cong tan, huong dan
than cap » thanh lap, thanh cac, than cua
khan cap » khan ap, khoan cam, phan cac

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: doi chieu sach - thanh trung ((cua nhung) OR (cua cong)) cong dan ((than cap) OR (khan cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - thanh trung ((cua nhung) or (cua cong)) cong dan ((than cap) OR (khan cap))~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sach - thanh trung ((cua nhung) or (cua cong)) cong dan ((than cap) OR (khan cap))*.
