Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh trang » thanh trung, hanh trinh, minh trang
cua nhung » va nhung
ho chieu » theo chieu, hoc thieu, doi chieu
cong tan » cong tac, cong thanh, cong ty
cong san » cong tac
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: ho chieu xanh - ((hanh trang) OR (canh tranh)) cua nhung ((cong tan) OR (cong san)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((hanh trang) or (canh tranh)) cua nhung ((cong tan) OR (cong san)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((hanh trang) or (canh tranh)) cua nhung ((cong tan) OR (cong san)) toan cau*.
