Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
chieu sach » chinh sach, chiet tach, chieu sang
hanh mang » nhanh mang, hanh trang, nhanh lang
cua nhung » va nhung
mang cua » manh cua, dung cua, ban cua
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
toan cau » toan cao, toan ban, toan tai
toan tap » toan ban

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 sach - hanh mang cua nhung ((cong dan) OR (cong tan)) ((toan cau) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - hanh mang cua nhung ((cong dan) or (cong tan)) ((toan cau) OR (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - hanh mang cua nhung ((cong dan) or (cong tan)) ((toan cau) OR (toan tap))*.
