Perhaps you should try some spelling variations:
chiet tach » chieu sach
hang doanh » hanh doanh, nhung doanh, dung doanh
doi chiet » doi chieu, doi chi, doi viet
van doanh » toan doanh, van dong, van thanh
cua nhung » va nhung
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
toan ban » van ban

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: doi chiet tach - ((hang doanh) OR (van doanh)) cua nhung ((cong dan) OR (cong san)) toan ban~.
• Adding a wildcard symbol may retrieve word variants: doi chiet tach - ((hang doanh) or (van doanh)) cua nhung ((cong dan) or (cong san)) toan ban*.
