Perhaps you should try some spelling variations:
chieu sach » chinh sach, chieu sang, chieu xanh
thanh dung » thanh duong, thanh tung, thanh hung
cua dung » cua dong, qua dung, cua rung
cua dang » cua cong, cua ban
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan cau » toan cao, toan ban, toan tap

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: theo ((chieu sach) or (chiet tach)) - thanh dung ((cua dung) OR (cua dang)) cong dan toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu sach) OR (chiet tach)) - thanh dung ((cua dung) OR (cua dang)) cong dan toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sach) or (chiet tach)) - thanh dung ((cua dung) OR (cua dang)) cong dan toan cau".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu sach) or (chiet tach)) - thanh dung ((cua dung) OR (cua dang)) cong dan toan cau*.
