Perhaps you should try some spelling variations:
hien xanh » hien hanh, hien nhanh, chieu xanh
thanh tra » thanh toan, thanh hoa
tuan dung » tuan duong, tran dung, tuan dang
tan dung » tran dung, van dung, dan dung
cong san » cong tac
san toan » van toan, dan toan, manh toan
toan ban » van ban

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: hoc hien xanh - thanh tra ((tuan dung) or (((tan dung) OR (tin dung)))) cong san toan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien xanh - thanh tra ((tuan dung) OR (((tan dung) OR (tin dung)))) cong san toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - thanh tra ((tuan dung) or (((tan dung) OR (tin dung)))) cong san toan ban*".
