(two) the creditor of the main contract uses fraud, coercion and other means to make the guarantor provide a guarantee against the true meaning. Article 40 of the Judicial Interpretation of the Guarantee Law stipulates: "If the debtor of the main contract makes the guarantor provide a guarantee against his true meaning by means of fraud or coercion, and the creditor knows or should know the facts of fraud or coercion, it shall be handled in accordance with the provisions of Article 30 of the Guarantee Law. "As can be seen from the above provisions, only when the creditor is malicious and the guarantor provides a guarantee against its true meaning can the guarantor be exempted from the guarantee liability. In this case, there is no evidence to prove that the creditor knew or should have known that the principal debtor cheated the guarantor, so the three guarantors should bear the guarantee responsibility for the loan of 500,000 yuan.
