Perhaps you should try some spelling variations:
chieu xanh » chieu sang, chieu tinh, hieu manh
chieu sach » chinh sach, chiet tach, chieu sang
anh manh » lanh manh, anh anh, anh danh
manh cua » doanh cua, ban cua
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
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: theo ((chieu xanh) OR (chieu sach)) - anh manh cua ban ((cong dan) OR (cong tan)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (chieu sach)) - anh manh cua ban ((cong dan) OR (cong tan)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (chieu sach)) - anh manh cua ban ((cong dan) OR (cong tan)) toan cau*.
