Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hoc chieu » hoc thieu, ho chieu, hoc hien
chinh lap » chinh la, chinh luan, chinh tai
lap dung » ap dung, lan dung, cap dung
cong dan » cong san, huong dan, cong tac
cong tan » cong tac, cong san, cong thanh
toan tap » toan 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: hoc chieu xanh - hanh chinh lap dung ((((cong dan) OR (cong dong))) OR (cong tan)) toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - hanh chinh lap dung ((((cong dan) OR (cong dong))) or (cong tan)) toan tap~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - hanh chinh lap dung ((((cong dan) OR (cong dong))) or (cong tan)) toan tap*.
