Perhaps you should try some spelling variations:
chieu tach » chieu sach, chiu trach, chieu tinh
chiet tach » chieu sach
chinh cua » chinh ca, chinh sua, hinh cua
cong cong » cong dong, trong cong, dung cong
cong tac » cong ty
toan cau » toan cao, toan tap, toan tai
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 tach) OR (chiet tach)) - hanh chinh cua cong cong tac ((toan cau) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu tach) or (chiet tach)) - hanh chinh cua cong cong tac ((toan cau) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu tach) or (chiet tach)) - hanh chinh cua cong cong tac ((toan cau) OR (toan ban))*.
