Perhaps you should try some spelling variations:
thong cong » trong cong, tong cong, phong chong
chieu xanh » chieu sach, chieu sang, chieu tinh
tieu xanh » tieu danh, dieu hanh, tien anh
hanh dung » thanh dung, anh dung, hanh dong
dung cua » dung luan, dung cho
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) OR (chieu xanh)) - hanh dung cua ((thong cong) OR (thong thong)) dan toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((tieu xanh) OR (chieu xanh)) - hanh dung cua ((thong cong) or (thong thong)) dan toan ban~".
• Adding a wildcard symbol may retrieve word variants: theo ((tieu xanh) OR (chieu xanh)) - hanh dung cua ((thong cong) or (thong thong)) dan toan ban*.
