Perhaps you should try some spelling variations:

chieu tach » chiet tach, chieu sach, chiu trach
canh manh » lanh manh, canh tranh, cach mang
manh cua » doanh cua, ban cua
cua bang » chua bang, cua ban, cua dang
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
phan cau » phan dau, phan cac, phan lap

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: theo chieu tach - canh manh cua bang ((cong dan) OR (cong san)) ((phan cau) OR (phan tu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu tach - canh manh cua bang ((cong dan) OR (cong san)) ((phan cau) or (phan tu))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu tach - canh manh cua bang ((cong dan) OR (cong san)) ((phan cau) or (phan tu))*.
