Perhaps you should try some spelling variations:
chieu sach » chinh sach, chieu sang, chieu xanh
canh doanh » hanh doanh, chinh doanh, doanh doanh
thong cong » trong cong, thong thong, phong chong
doanh cua » doanh luan
tong cong » trong cong, cong cong, dung cong
dan toan » van toan, dan than, manh toan
toan tap » toan 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 ((chieu sach) OR (chiet tach)) - canh doanh cua ((thong cong) OR (tong cong)) dan toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu sach) OR (chiet tach)) - canh doanh cua ((thong cong) or (tong cong)) dan toan tap~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu sach) OR (chiet tach)) - canh doanh cua ((thong cong) or (tong cong)) dan toan tap*.
