Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
truong cua » truong quan, truong cao, huong cua
truong ca » truong cao, truong va, trong ca
ho chieu » theo chieu, hoc thieu, doi chieu
cong ban » cong bang, cong san, cong dan
cong tan » cong tac, cong san, cong thanh
tai cac » tai cuc

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: ho chieu sach - hanh ((truong cua) OR (truong ca)) bang ((cong ban) OR (cong tan)) tai cac~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - hanh ((truong cua) OR (truong ca)) bang ((cong ban) or (cong tan)) tai cac~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - hanh ((truong cua) OR (truong ca)) bang ((cong ban) or (cong tan)) tai cac*.
