Perhaps you should try some spelling variations:
theo chieu » theo tieu, theo chu, thi chieu
hanh doanh » hang doanh, chinh doanh, doanh doanh
nhung cong » dung cong, thong cong, nhung don
hang cong » dang cong, hang nong, bang cong
tan thanh » tran thanh, tang thanh, toan thanh
thanh tap » thanh lap, thanh tai, thanh tay
ho chieu » hoc thieu, doi chieu, mot chieu

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) OR (ho chieu)) sach - hanh doanh tai ((nhung cong) OR (hang cong)) tan thanh tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) OR (ho chieu)) sach - hanh doanh tai ((nhung cong) or (hang cong)) tan thanh tap~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) OR (ho chieu)) sach - hanh doanh tai ((nhung cong) or (hang cong)) tan thanh tap*.
