Legal analysis: the guarantor's guarantee period shall be agreed upon by the parties through consultation. Where the guarantor of a general guarantee and the creditor have not agreed on the guarantee period, the guarantee period shall be six months from the expiration of the performance period of the principal debt. If the agreement is too long, it will be regarded as unclear, and the guarantee period will be two years.

Legal basis: Article 692 of the Civil Code of People's Republic of China (PRC) * * * The guarantee period is the period that the guarantor decides to undertake the guarantee responsibility, and it is not suspended, interrupted or extended. The creditor and the guarantor may agree on a guarantee period, but if the agreed guarantee period expires before or at the same time as the performance period of the principal debt, it is deemed that there is no agreement; If there is no agreement or the agreement is unclear, the guarantee period shall be six months from the date of expiration of the main debt performance period. Where the creditor and the debtor have not agreed or clearly agreed on the time limit for the performance of the principal debt, the guarantee period shall be counted from the date when the grace period for the creditor to request the debtor to perform the debt expires.
