Perhaps you should try some spelling variations:
chieu sach » chinh sach, chieu sang, chieu xanh
hanh manh » hanh mang, lanh manh, hoang manh
dong cong » duong cong, dung cong, dang cong
manh cua » doanh cua, ban cua
cua dong » chua dong, cua cong, cua dang
cong san » cong tac
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 ((chieu sach) OR (chiet tach)) - hanh manh cua dong cong san ((toan cau) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sach) OR (chiet tach)) - hanh manh cua dong cong san ((toan cau) or (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu sach) OR (chiet tach)) - hanh manh cua dong cong san ((toan cau) or (toan tap))*.
