Perhaps you should try some spelling variations:
thiet tach » chiet tach, thien hach, thuat tach
hanh dung » thanh dung, anh dung, hanh dong
ho thiet » hoc thiet, hoa thiet, so thiet
han dung » chan dung, han duong, phan dung
cong tan » cong san, cong thanh, cong ty
cong tac » cong ty
toan tap » toan 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 thiet tach - hanh chinh ((han dung) OR (hanh dung)) ((cong tan) OR (cong tac)) toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho thiet tach - hanh chinh ((han dung) OR (hanh dung)) ((cong tan) or (cong tac)) toan tap~".
• Adding a wildcard symbol may retrieve word variants: ho thiet tach - hanh chinh ((han dung) OR (hanh dung)) ((cong tan) or (cong tac)) toan tap*.
