Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
ngan thanh » nganh thanh, ngon thanh, nhan thanh
cong thanh » dong thanh, cong trinh, truong thanh
doi chieu » doc hieu, doi chi, ho chieu
cong tan » cong tac, cong san, cong ty
tuan cao » toan cao, juan cao, quang cao

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - hanh chinh ngan thanh ((cong thanh) OR (cong tan)) tuan cao~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sach - hanh chinh ngan thanh ((cong thanh) OR (cong tan)) tuan cao*.
