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