Perhaps you should try some spelling variations:
doanh doanh » doanh hoan, doanh thanh, dong doanh
chieu xanh » chieu sach, chieu sang, chieu tinh
cong cong » cong dong, trong cong, dung cong
ho chieu » theo chieu, hoc thieu, doi chieu
cong dan » cong san, cong tan, huong dan
toan cao » toan tap
toan ban » van 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: ho chieu xanh - ((doanh doanh) OR (toan doanh)) cua cong cong dan ((toan cao) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((doanh doanh) OR (toan doanh)) cua cong cong dan ((toan cao) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((doanh doanh) OR (toan doanh)) cua cong cong dan ((toan cao) or (toan ban))*.
