Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
chieu xanh » chieu sach, chieu sang, chieu tinh
doanh cua » doanh luan
dang cong » dung cong
dung cua » dung luan, dung cho
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: theo chieu xanh - hanh ((dung cua) OR (doanh cua)) dang cong dan ((toan cao) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - hanh ((dung cua) or (doanh cua)) dang cong dan ((toan cao) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - hanh ((dung cua) or (doanh cua)) dang cong dan ((toan cao) OR (toan ban))*.
