Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
chieu xanh » chieu sach, chieu sang, chieu tinh
khoan cam » khoa cam, khoan va, phan cam
cua dung » cua dang, qua dung, cua rung
cua dong » chua dong, cua cong, cua dang
cong dan » cong san, cong tan, huong dan
than cap » khan cap, thanh lap, thanh cac

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - canh tranh ((cua dung) OR (cua dong)) cong dan ((than cap) OR (khoan cam))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - canh tranh ((cua dung) OR (cua dong)) cong dan ((than cap) OR (khoan cam))*.
