Friend, under normal circumstances, there is no interest-free loan, but it depends on the support and support of local governments for agricultural machinery. At present, the Ministry of Finance and local governments subsidize agricultural machinery heavily, generally between 30% and 70%, but the two books are still limited, so the interest-free loans you mentioned are usually less, except for government-supported entrepreneurial projects.
If it is a business fairy supported by the government, it needs to be reported to the project book for approval.
