Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
chuc danh » chuc nganh, thuc hanh, chuc nang
hanh dong » anh dong, ha dong
dung cong » dung trong
chu xanh » chu manh, chua xang, chu thanh
cong tan » cong tac, cong san, cong thanh
tan than » tan thanh, tan tran, ban than
than cau » toan cau, phan cau, than cap
dong su » dang su, dong tu, dong luc

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: theo ((((chu xanh) OR (chuc danh))) OR (chieu xanh)) - hanh dong su dung cong tan than cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((((chu xanh) or (chuc danh))) or (chieu xanh)) - hanh dong su dung cong tan than cau*.
