Perhaps you should try some spelling variations:
nhung phuong » dung phuong, nhu phuong, truong phuong
nhung huong » nhung tuong, nhung cong, nhung dung
theo chieu » theo tieu, ho chieu, theo chu
chieu xanh » chieu sach, chieu sang, chieu tinh
tranh cua » doanh cua, manh cua
toan cau » toan ban, toan tap, toan tai
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 chieu xanh - canh tranh cua ((nhung huong) OR (nhung phuong)) dan ((toan cau) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - canh tranh cua ((nhung huong) or (nhung phuong)) dan ((toan cau) OR (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - canh tranh cua ((nhung huong) or (nhung phuong)) dan ((toan cau) OR (toan cao))*.
