Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
tieu xanh » tieu danh, chieu xanh, dieu hanh
hanh luan » khanh luan, hang luan, hanh luat
van nhung » van nhuong, va nhung, van hung
cong dan » cong san, cong tan, huong dan
toan cau » toan cao, toan ban, toan tai
toan tap » toan ban

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu xanh - hanh luan van nhung cong dan ((toan cau) OR (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - hanh luan van nhung cong dan ((toan cau) OR (toan tap))*.
