Perhaps you should try some spelling variations:
tieu xanh » tieu danh, chieu xanh, dieu hanh
cong bang » cuong bang, dong bang, hong bang
anh bang » anh hoang, anh quang, tinh bang
anh dang » anh dong, anh dung, anh danh
cong ban » cong san, cong tan, cong dan
than cap » khan cap, thanh lap, thanh cac
va dung » van dung, va duong, vat dung

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 - ((anh bang) OR (anh dang)) va dung ((cong ban) OR (cong bang)) than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu xanh - ((anh bang) or (anh dang)) va dung ((cong ban) OR (cong bang)) than cap~".
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - ((anh bang) or (anh dang)) va dung ((cong ban) OR (cong bang)) than cap*.
