Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh doanh » chinh doanh, doanh doanh, kinh doanh
hang doanh » nhung doanh, van doanh, dung doanh
quang dung » quang trung, ung dung, cuong dung
ho chieu » theo chieu, hoc thieu, doi chieu
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: ho chieu xanh - ((hanh doanh) OR (hang doanh)) quang dung ((cong dan) OR (cong tan)) van ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((hanh doanh) OR (hang doanh)) quang dung ((cong dan) or (cong tan)) van ban~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((hanh doanh) OR (hang doanh)) quang dung ((cong dan) or (cong tan)) van ban*.
