Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
chiet tach » chieu sach
nhung cong » dung cong, thong cong, hang cong
danh nhat » doanh nhat, danh nhan, doanh nhan
dang nhat » dung nhan, dung nha
cua nhung » va nhung
cong tan » cong tac, cong san, cong thanh
tan toan » tan tran, tap toan, van toan
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 (chiet tach)) - ((danh nhat) OR (dang nhat)) cua nhung cong tan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (chiet tach)) - ((danh nhat) OR (dang nhat)) cua nhung cong tan toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (chiet tach)) - ((danh nhat) OR (dang nhat)) cua nhung cong tan toan cau*.
