Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hieu manh » chieu xanh, hieu nganh, dieu hanh
thanh tra » thanh toan, thanh hoa
van nhung » van nhuong, va nhung, van hung
thanh cac » hanh cac, thanh bac, thanh ca
hoc hieu » hoc thieu, hoc hien, doc hieu
cong dan » cong san, cong tan, huong dan
than cap » thanh lap, than cua, than va
khan cap » khan ap, khoan cam, phan cac
tra van » tran van, ta van, trang van

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: hoc hieu manh - thanh tra van nhung cong dan ((((than cap) OR (thanh cac))) OR (khan cap))~.
• Adding a wildcard symbol may retrieve word variants: hoc hieu manh - thanh tra van nhung cong dan ((((than cap) or (thanh cac))) or (khan cap))*.
