Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh trung » thanh trung, hanh trang, manh trung
manh hung » anh huong
ho chieu » theo chieu, hoc thieu, doi chieu
cong tan » cong tac, cong thanh, cong ty
cong san » cong tac
than cau » toan cau, phan cau, than cap
ap dung » xay dung, van dung

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 trung) OR (manh hung)) ap dung ((cong tan) OR (cong san)) than cau~.
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((hanh trung) or (manh hung)) ap dung ((cong tan) or (cong san)) than cau*.
