Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
chieu xanh » chieu sach, chieu sang, chieu tinh
cong dan » huong dan, cong dong, cong tac
cong tan » cong tac, cong thanh, cong ty
cong san » cong tac
toan ban » van ban
can ban » van ban

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

• Performing a fuzzy search may retrieve terms with similar spellings: theo chieu xanh - can ban va nhung ((((cong dan) OR (cong tan))) or (cong san)) toan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu xanh - can ban va nhung ((((cong dan) OR (cong tan))) OR (cong san)) toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - can ban va nhung ((((cong dan) OR (cong tan))) or (cong san)) toan ban*".
