Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
chieu sach » chinh sach, chiet tach, chieu sang
hanh trung » thanh trung, hanh trang, manh trung
trung cua » truong cua, trung tuan, trung cap
cua dang » cua cong, cua ban
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
toan ban » van 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 tinh) OR (chieu sach)) - hanh trung cua dang ((cong dan) OR (cong tan)) toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu tinh) or (chieu sach)) - hanh trung cua dang ((cong dan) OR (cong tan)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu tinh) or (chieu sach)) - hanh trung cua dang ((cong dan) OR (cong tan)) toan ban*.
