Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
cong cong » cong dong, trong cong, dung cong
ho chieu » theo chieu, hoc thieu, doi chieu
anh dung » anh huong, sach dung, ap dung
anh dong » anh huong, anh son
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cau » toan cau, phan cau, than cap

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 - ((((anh dung) OR (ung dung))) OR (anh dong)) cua cong cong dan than cau~.
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((((anh dung) or (ung dung))) or (anh dong)) cua cong cong dan than cau*.
