Perhaps you should try some spelling variations:
hanh tung » thanh tung, manh tung, hanh dung
hanh mang » nhanh mang, hanh trang, nhanh lang
luan dang » luan nang, luan danh, luan dong
dang cong » dung cong
25 trieu » 30 trieu
cong dan » cong san, cong tan, huong dan
toan cau » toan cao, toan tap, toan tai
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: 25 trieu tinh - ((hanh tung) OR (hanh mang)) luan dang cong dan ((toan cau) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "25 trieu tinh - ((hanh tung) or (hanh mang)) luan dang cong dan ((toan cau) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: 25 trieu tinh - ((hanh tung) or (hanh mang)) luan dang cong dan ((toan cau) OR (toan ban))*.
