Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh trinh » canh tranh, hanh chinh
cua phuong » cuu phuong, cuc phuong, luan phuong
ca thuong » cao thuong, cua thuong, va thuong
ho chieu » theo chieu, hoc thieu, doi chieu
cong dan » cong san, cong tan, huong dan
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: ho chieu xanh - hanh trinh ((cua phuong) OR (ca thuong)) cong dan ((toan cau) OR (toan cao))~.
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh trinh ((cua phuong) or (ca thuong)) cong dan ((toan cau) or (toan cao))*.
