Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
chieu tinh » trieu tinh, lieu tinh, chau tinh
anh dong » anh huong, anh son
dong cua » dung cua, cong cua, huong cua
cua tong » cua cong, cua dong, cua nong
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh

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) OR (chieu tinh)) - anh dong cua tong ((cong dan) OR (cong tan)) van ban~.
• Adding a wildcard symbol may retrieve word variants: theo ((chieu sach) or (chieu tinh)) - anh dong cua tong ((cong dan) or (cong tan)) van ban*.
