Interest-free loans can't be handled. The state has very strict requirements for interest-free loans. You can't just find relationships. Don't trust others to help you with interest-free loans. There will be no pie in the sky. I suggest you make a careful decision. If your rights and interests are infringed, please call the police in time.
If you think you have encountered usury, you can negotiate with each other first. Secondly, if negotiation fails, you can choose a civil lawsuit, or you can bring a civil lawsuit directly without consultation. Finally, if violent collection is involved, you can choose to call 1 10 to call the police.
