Perhaps you should try some spelling variations:
chieu xanh » chieu sang, chieu tinh, hieu manh
chieu sach » chinh sach, chiet tach, chieu sang
hanh dung » thanh dung, anh dung, hanh dong
dang cong » dung cong
dung cua » dung luan, dung cho
cua dang » cua cong, cua ban
dan toan » van toan, manh toan, xuan toan
dan than » dan chan, ban than, van than

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 xanh) OR (chieu sach)) - hanh dung cua dang cong ((dan toan) OR (dan than)) cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (chieu sach)) - hanh dung cua dang cong ((dan toan) or (dan than)) cau*.
