Perhaps you should try some spelling variations:
chinh doanh » kinh doanh
chieu sach » chinh sach, chieu sang, chieu xanh
doanh cua » doanh luan
phan cong » thanh cong
ban cong » bang cong, van cong, ban huong
ban than » ban thanh, van thanh, ban hang
than cao » toan cao, thai cao, than cap

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: ho ((chiet tach) OR (chieu sach)) - chinh doanh cua ((ban cong) OR (phan cong)) ban than cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chiet tach) OR (chieu sach)) - chinh doanh cua ((ban cong) or (phan cong)) ban than cao~".
• Adding a wildcard symbol may retrieve word variants: ho ((chiet tach) OR (chieu sach)) - chinh doanh cua ((ban cong) or (phan cong)) ban than cao*.
