Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
tieu xanh » tieu danh, dieu hanh, tien anh
dieu danh » dieu hanh, tieu danh, dia danh
dung cong » dung trong
hanh ban » thanh ban, hang ban, hanh san
cua dung » cua dang, cua dong, qua dung
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than ban » thanh ban, toan ban, than man
ban cua » ban quan

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 ((((tieu xanh) OR (chieu xanh))) OR (dieu danh)) - hanh ban cua dung cong dan than ban~.
• Adding a wildcard symbol may retrieve word variants: theo ((((tieu xanh) or (chieu xanh))) or (dieu danh)) - hanh ban cua dung cong dan than ban*.
