Perhaps you should try some spelling variations:
chien thuat » thien thuat, hien thuan, trien thuat
theo chieu » theo tieu, ho chieu, theo chu
chieu xanh » chieu sach, chieu sang, chieu tinh
chinh thuc » chinh phuc, hinh thuc, trinh thuc
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
toan ban » van ban

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 - hanh ((chinh thuc) OR (chien thuat)) nhung ((cong dan) OR (cong tan)) toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - hanh ((chinh thuc) or (chien thuat)) nhung ((cong dan) OR (cong tan)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - hanh ((chinh thuc) or (chien thuat)) nhung ((cong dan) OR (cong tan)) toan ban*.
