Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
tieu xanh » tieu danh, chieu xanh, dieu hanh
hanh tran » hanh trang, thanh tran, hanh tram
thanh tra » thanh toan, thanh hoa
van nhung » van nhuong, va nhung, van hung
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cap » khan cap, thanh lap, thanh cac

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: theo tieu xanh - ((hanh tran) OR (thanh tra)) van nhung cong dan than cap~.
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - ((hanh tran) or (thanh tra)) van nhung cong dan than cap*.
