Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh dung » thanh dung, anh dung, hanh dong
tong cong » trong cong, cong cong, dung cong
dung cua » dung luan, dung cho
cua tong » cua cong, cua dong, cua nong
dan toan » van toan, dan than, manh toan
van tuan » van quan, van ban, anh tuan

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