Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
thanh tung » thanh cong
thanh toan » thanh hoa, thanh san, tinh toan
hoc thieu » toc thieu, hoc hien
hang cong » dang cong, bang cong, thanh cong
hang nong » thang long, han tong
toan cao » toan ban, toan tap

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 thieu xanh - ((hanh chinh) OR (thanh tung)) cua ((hang cong) OR (hang nong)) thanh toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - ((hanh chinh) or (thanh tung)) cua ((hang cong) OR (hang nong)) thanh toan cao~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - ((hanh chinh) or (thanh tung)) cua ((hang cong) OR (hang nong)) thanh toan cao*.
