Perhaps you should try some spelling variations:
chieu sang » chieu sach, hieu lang, nhieu tang
chieu xanh » chieu sach, chieu tinh, hieu manh
hanh dung » thanh dung, anh dung, hanh dong
luan tong » luan tuong, luan cong, luan dong
tong cong » trong cong, cong cong, dung cong
cong tac » cong ty
tac tran » tan tran, tac trai, tac tren
tran cau » tran chau, toan cau, ran cau

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 ((chieu sang) OR (chieu xanh)) - hanh dung luan tong cong tac tran cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((chieu sang) or (chieu xanh)) - hanh dung luan tong cong tac tran cau*.
