Perhaps you should try some spelling variations:
luan trong » quan trong, luat trong, luan tuong
theo tien » theo tieu, theo tcvn, tien tien
thuc tien » thuc hien
hanh tang » hanh trang, anh tang, hanh mang
tang luan » dung luan
cong dan » cong san, cong tan, cong dong
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 tien) OR (thuc tien)) thinh - hanh tang luan trong ((cong dan) OR (huong dan)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo tien) OR (thuc tien)) thinh - hanh tang luan trong ((cong dan) or (huong dan)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((theo tien) OR (thuc tien)) thinh - hanh tang luan trong ((cong dan) or (huong dan)) toan cau*.
