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
trong dan » trong dang, trong san, trong ban
trong tan » trong quan, trong cac, trong ca
dung cua » dung luan, dung cho
cua dung » cua dang, cua dong, qua dung
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 sang) OR (chieu xanh)) - hanh dung cua dung ((trong dan) OR (trong tan)) than cau~.
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) or (chieu xanh)) - hanh dung cua dung ((trong dan) or (trong tan)) than cau*.
