Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
hieu manh » chieu xanh, hieu nganh, dieu hanh
hanh dung » thanh dung, anh dung, hanh dong
tong cong » trong cong, cong cong, dung cong
cho tong » cho trong, cho tuong, cho cong
cong tac » cong ty
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 ((hieu manh) OR (chieu sach)) - hanh dung cho tong cong tac ((toan cau) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((hieu manh) or (chieu sach)) - hanh dung cho tong cong tac ((toan cau) OR (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: theo ((hieu manh) or (chieu sach)) - hanh dung cho tong cong tac ((toan cau) OR (toan tap))*.
