You can't. The loan contract of Dida Insurance has been signed and has legal effect. There is a loan relationship between the borrower and Dida Insurance Company, and repayment must be made according to the contract. If the borrower fails to repay the loan as agreed in the contract, it will be liable for breach of contract, including paying overdue penalty interest and affecting personal credit information, so the remaining loan of Dida Insurance cannot be repaid.
