First, solve the problem through consultation. If negotiation fails, pre-litigation preservation can be adopted (that is, seizure and freezing of the assets and property of the defendant infringer), and attention should be paid to the two-year statute of limitations protected by the General Principles of the Civil Law. If the two-year period is approaching, various methods can be taken to interrupt the limitation of action, such as finding ways to make the infringer actively or passively repay part of the money (even if the infringer deducts the infringer's money) and keep the bank account for repayment as evidence.

However, it should be noted that if other cases involving enterprises are involved, they shall be handled by the parties themselves. If the enterprise owes a loan to the bank, the bank can still claim civil rights according to the contract, and can also claim criminal responsibility at the same time or separately. In other words, banks can ignore the internal triangular debts of enterprises, and financial lending disputes can be solved independently without interference from other cases.
