Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh tranh » canh tranh, hanh trinh, hanh trang
ho chieu » theo chieu, hoc thieu, doi chieu
tranh va » tranh van, trang va, trinh va
cong dan » cong san, cong dong, cong tac
cong tan » cong tac, cong san, cong thanh
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 tranh va nhung ((((cong dan) OR (huong dan))) OR (cong tan)) toan cau~.
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh tranh va nhung ((((cong dan) or (huong dan))) or (cong tan)) toan cau*.
