Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
chieu xanh » chieu sach, chieu sang, chieu tinh
tung cap » trung cap, thong cap, trong cap
cung cap » trung cap
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
than cap » khan cap, thanh lap, thanh cac

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