Borrowing the new to repay the old, also known as repaying the loan by loan, generally refers to the behavior that the borrower can't repay the loan on time after the loan expires, and the lender signs a new loan contract with the borrower to reissue the loan to repay part or all of the original loan, which is one of the commonly used loan restructuring means of commercial banks and other financial institutions.
The form of loan repayment is still discouraged, after all, it may happen in the middle, but if the interest is not high, lending is also an emergency means.
