1, you can sue, but if the defendant's defense has exceeded the limitation of action, the court will reject the claim.

2. Loans beyond the limitation of action can also be prosecuted. If the defendant does not appear in court at the trial, the court will still support his claim, even though the statute of limitations has expired.

3. For the loan beyond the limitation of action, the lender issues a notice of overdue payment to the borrower. If the debtor signs or seals the notice, it will be regarded as a reaffirmation of the original debt, and the creditor's rights and debts are still protected by law.

4. For the loan beyond the limitation of action, both parties reach a repayment agreement on the original debt, which belongs to a new creditor-debtor relationship, and the repayment agreement is protected by law.
