Perhaps you should try some spelling variations:
thong cong » trong cong, tong cong, thong thong
thanh toan » thanh hoa, thanh san, tinh toan
hien xanh » hien hanh, hien nhanh, chieu xanh
van thong » van thuong, van phong, va thong
thanh ta » thanh tra, thanh tai, thanh tay
dan toan » van toan, dan than, manh toan
ta van » tan van, tap van, va 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 hien xanh - thanh ta van thong cong ((dan toan) OR (((thanh toan) OR (anh tuan)))) cao~.
• Adding a wildcard symbol may retrieve word variants: hoc hien xanh - thanh ta van thong cong ((dan toan) or (((thanh toan) or (anh tuan)))) cao*.
