If you look carefully, you will find it. Usury is illegal. Usury is not more than four times the interest rate of similar loans of banks (including the principal interest rate) and is protected by law. Loans can be recovered through negotiation, mediation, arbitration and litigation.

Article 6 of Several Opinions of People's Courts on Handling Lending Cases stipulates that the interest rate of private lending can be appropriately higher than that of banks, and local people's courts can specifically grasp it according to the actual situation in the region, but the maximum interest rate shall not exceed 4 times (including interest rate) of similar loans of banks. Beyond this limit, the excess interest will not be protected.

Article 7 stipulates that the lender shall not include interest in the principal to seek high profits. If it is found during the trial that the creditor included the interest in the principal to calculate compound interest, if the interest rate exceeds the limit stipulated in Article 6, the excess interest will not be protected.
