Perhaps you should try some spelling variations:
doanh cuong » doan cuong, doanh thuong, dinh cuong
theo chieu » theo tieu, ho chieu, theo chu
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh doanh » hang doanh, chinh doanh, doanh doanh
cuong dung » tuong duong, ung dung, thong dung
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh

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 xanh - hanh doanh cuong dung ((cong dan) OR (cong tan)) van ban~.
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - hanh doanh cuong dung ((cong dan) or (cong tan)) van ban*.
