Perhaps you should try some spelling variations:
nhuong cong » nhung cong, luong cong, duong cong
chieu sach » chinh sach, chiet tach, chieu sang
van nhuong » van chuong, van phuong, van huong
thanh toan » thanh hoa, thanh san
hanh dang » hanh dong, anh dang, hanh dung
dang van » hoang van, hang va

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 ((dieu hanh) OR (chieu sach)) - hanh dang van nhuong cong ((thanh toan) OR (tinh toan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((dieu hanh) or (chieu sach)) - hanh dang van nhuong cong ((thanh toan) OR (tinh toan)) cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((dieu hanh) or (chieu sach)) - hanh dang van nhuong cong ((thanh toan) OR (tinh toan)) cau*.
