Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
chieu xanh » chieu sach, chieu sang, chieu tinh
thanh tung » thanh cong
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
than cau » toan cau, than cap, thanh chau
phan cau » phan dau, phan cac, phan tu
tung ho » tuong ho, trung hoc, trung hoa
ho dung » hoc dung, hoi dung, so dung

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 - thanh tung ho dung ((cong dan) OR (cong san)) ((than cau) OR (phan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - thanh tung ho dung ((cong dan) OR (cong san)) ((than cau) or (phan cau))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - thanh tung ho dung ((cong dan) OR (cong san)) ((than cau) or (phan cau))*.
