Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
nhung cong » dung cong, thong cong, hang cong
hanh tang » hanh trang, anh tang, hanh mang
cua nhung » va nhung
chu manh » ho manh, chu han, chu van
tang cua » mang cua, hang cua, tang luan
cong dan » cong san, cong tan, huong dan
toan cau » toan cao, toan ban, toan tai
toan tap » toan 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 ((chu manh) OR (chieu sach)) - hanh tang cua nhung cong dan ((toan cau) OR (toan tap))~.
• Adding a wildcard symbol may retrieve word variants: theo ((chu manh) or (chieu sach)) - hanh tang cua nhung cong dan ((toan cau) or (toan tap))*.
