Perhaps you should try some spelling variations:
nhung phuong » dung phuong, nhu phuong, truong phuong
nhung tuong » nhung huong, hung vuong, nhung cong
chiet tach » chieu sach
hanh trinh » canh tranh, hanh chinh
trinh cua » tinh cua, trinh luat, trinh quan
ho chiet » ho chieu, ho thiet, hoc thiet
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.

• If you are trying to use Boolean operators, they must be ALL CAPS: ho chiet tach - hanh trinh cua ((nhung tuong) OR (nhung phuong)) manh ((toan cau) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chiet tach - hanh trinh cua ((nhung tuong) OR (nhung phuong)) manh ((toan cau) or (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: ho chiet tach - hanh trinh cua ((nhung tuong) OR (nhung phuong)) manh ((toan cau) or (toan tap))*.
