Perhaps you should try some spelling variations:
chieu xanh » chieu sang, chieu tinh
chieu sach » chinh sach, chiet tach, chieu sang
thanh dung » thanh duong, thanh tung, thanh hung
hieu manh » hieu nganh, dieu hanh, hien hanh
dung cong » dung trong
dung cua » dung luan, dung cho
cua dung » cua dang, cua dong, qua dung
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 (chieu sach))) OR (hieu manh)) - thanh dung cua dung cong tan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((((chieu xanh) OR (chieu sach))) or (hieu manh)) - thanh dung cua dung cong tan toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((((chieu xanh) OR (chieu sach))) or (hieu manh)) - thanh dung cua dung cong tan toan cau*.
