Perhaps you should try some spelling variations:
hanh doanh » hang doanh, chinh doanh, doanh doanh
tieu sach » chieu sach, dien sach, te sach
doanh cua » doanh luan
thanh cau » thanh chau, thanh mau, nhanh cau
cua dang » cua cong, cua ban
cong van » cong vang, song van, cong tan
cong san » cong tac

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu sach - hanh doanh cua dang ((cong van) OR (cong san)) thanh cau~".
• Adding a wildcard symbol may retrieve word variants: theo tieu sach - hanh doanh cua dang ((cong van) OR (cong san)) thanh cau*.
