Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
anh bang » anh hoang, anh quang, tinh bang
bang cua » ban cua, mang cua, hang cua
cua hang » cua dang, cua nhung, cua cong
cong tac » cong ty
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 sang)) - anh bang cua hang ((cong san) OR (cong tac)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sang)) - anh bang cua hang ((cong san) or (cong tac)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) OR (chieu sang)) - anh bang cua hang ((cong san) or (cong tac)) toan cau*.
