Perhaps you should try some spelling variations:
chieu sach » chinh sach, chieu sang, chieu xanh
tong cong » trong cong, cong cong, dung cong
hanh ban » thanh ban, hang ban, hanh san
cua tong » cua cong, cua dong, cua nong
cong dan » cong san, cong tan, huong dan
toan cau » toan ban, toan tap, toan tai
toan cao » toan ban, toan tap
ban cua » ban quan

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 ((chiet tach) OR (chieu sach)) - hanh ban cua tong cong dan ((toan cau) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chiet tach) OR (chieu sach)) - hanh ban cua tong cong dan ((toan cau) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chiet tach) OR (chieu sach)) - hanh ban cua tong cong dan ((toan cau) or (toan cao))*.
