Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
hanh trung » thanh trung, hanh trang, manh trung
trung tuan » trung thanh, trung tam, tran tuan
hoc chieu » hoc thieu, ho chieu, hoc hien
tuan dang » tran dang, tuan bang, tuan dung
cong tan » cong tac, cong san, cong thanh
toan tai » toan tap, doanh tai, toan cao
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: hoc chieu sach - hanh trung tuan dang ((cong tan) OR (huong dan)) ((toan tai) OR (toan ban))~.
• Adding a wildcard symbol may retrieve word variants: hoc chieu sach - hanh trung tuan dang ((cong tan) or (huong dan)) ((toan tai) or (toan ban))*.
