Perhaps you should try some spelling variations:
theo chieu » theo tieu, theo chu, thi chieu
thong cong » trong cong, tong cong, thong thong
chinh cua » chinh ca, chinh sua, hinh cua
cua thong » cua thuong, cua khong, cua tong
ho chieu » hoc thieu, doi chieu, mot chieu
cong dan » cong san, cong tan, huong dan

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) OR (ho chieu)) xanh - hanh chinh cua thong cong dan ((toan ban) OR (van ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) or (ho chieu)) xanh - hanh chinh cua thong cong dan ((toan ban) OR (van ban))~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (ho chieu)) xanh - hanh chinh cua thong cong dan ((toan ban) OR (van ban))*.
