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
dung cong » dung trong
thanh cac » hanh cac, thanh bac, thanh ca
mang cua » manh cua, dung cua, ban cua
cua dung » cua dang, cua dong, qua dung
cong tan » cong tac, cong san, cong thanh
than cap » khan cap, thanh lap, than cua
phan cac » nhan cach, phan dau, 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 sach - hanh mang cua dung cong tan ((((than cap) OR (thanh cac))) OR (phan cac))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - hanh mang cua dung cong tan ((((than cap) OR (thanh cac))) or (phan cac))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - hanh mang cua dung cong tan ((((than cap) OR (thanh cac))) or (phan cac))*.
