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