Perhaps you should try some spelling variations:
chieu xanh » chieu sang, chieu tinh, hieu manh
chieu sach » chinh sach, chiet tach, chieu sang
hanh mang » nhanh mang, hanh trang, nhanh lang
cua nhung » va nhung
mang cua » manh cua, dung cua, ban cua
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
toan cau » toan cao, toan ban, toan tap

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: doi ((chieu xanh) OR (chieu sach)) - hanh mang cua nhung ((cong dan) OR (cong san)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) or (chieu sach)) - hanh mang cua nhung ((cong dan) OR (cong san)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu xanh) or (chieu sach)) - hanh mang cua nhung ((cong dan) OR (cong san)) toan cau*.
