Perhaps you should try some spelling variations:
canh doanh » chinh doanh, doanh doanh, kinh doanh
hanh doanh » hang doanh, chinh doanh, doanh doanh
hien xanh » hien hanh, hien nhanh, chieu xanh
cong cong » cong dong, trong cong, dung cong
manh toan » thanh toan, anh tuan, tinh toan
dan toan » van toan, dan than, xuan toan

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 - ((canh doanh) OR (hanh doanh)) cua cong cong ((dan toan) OR (manh toan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - ((canh doanh) or (hanh doanh)) cua cong cong ((dan toan) OR (manh toan)) cau~".
• Adding a wildcard symbol may retrieve word variants: hoc hien xanh - ((canh doanh) or (hanh doanh)) cua cong cong ((dan toan) OR (manh toan)) cau*.
