Perhaps you should try some spelling variations:
thanh dung » thanh duong, thanh tung, thanh hung
tieu xanh » tieu danh, chieu xanh, dieu hanh
hanh dung » anh dung, hanh dong, manh dung
cua thong » cua thuong, cua khong, suat thong
cua tong » cua cong, cua dong, cua nong
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
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 tieu xanh - ((hanh dung) OR (thanh dung)) ((cua thong) OR (cua tong)) cong dan toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu xanh - ((hanh dung) or (thanh dung)) ((cua thong) OR (cua tong)) cong dan toan ban~".
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - ((hanh dung) or (thanh dung)) ((cua thong) OR (cua tong)) cong dan toan ban*.
