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