For private loans with regular repayment, the limitation of action is 3 years from the date of the expiration of the repayment period, and the right to request protection from the people's court is lost after the expiration.

For private lending with regular repayment, if the debtor fails to perform the debt after the agreed time limit expires and issues a debt bill with no repayment date, it shall be deemed as the interruption of the limitation of action, and the limitation of action shall be recalculated from the second day after receiving the debt bill (3 years).

The irregular repayment of private loans, that is, private loans without repayment date, is not limited by the statute of limitations, but by the maximum protection period of 20 years.

For non-standard private lending, if the borrower explicitly refuses to repay (of course, the borrower will prove that he has explicitly refused to repay), the three-year limitation period will apply from the date when the borrower explicitly refuses to repay.

For private lending beyond the limitation of action, if both parties reach a repayment agreement on the original debt, or the borrower signs the dunning notice, it will be regarded as a reaffirmation of the original debt, and the relationship between creditor's rights and debts should be protected by law.
