Perhaps you should try some spelling variations:
dung phuong » dung thuong, bang phuong, dung chung
phuong dan » phuong danh, phuong doan, huong dan
tieu xanh » tieu danh, chieu xanh, tien anh
hanh tung » thanh tung, manh tung, hanh dung
hanh mang » nhanh mang, hanh trang, nhanh lang
luan dung » lan dung, luan dong, luan hung
dan toan » van toan, dan than, manh toan
toan cau » toan cao, toan ban, toan tap

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 (dieu hanh)) - ((hanh tung) OR (hanh mang)) luan dung phuong dan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((tieu xanh) OR (dieu hanh)) - ((hanh tung) or (hanh mang)) luan dung phuong dan toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((tieu xanh) OR (dieu hanh)) - ((hanh tung) or (hanh mang)) luan dung phuong dan toan cau*.
