Legal analysis: Guarantor can't cancel the guarantee unless the creditor agrees. Because guarantee is a kind of contract, as long as the guarantee contract is signed, if both parties to the guarantee contract cannot reach an agreement to terminate the guarantee contract, the guarantor must bear the guarantee responsibility. However, it is worth noting that there are problems during the guarantee period and there are cases of fraudulent guarantee. 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 creditor fails to bring a lawsuit or apply for arbitration against the debtor within the guarantee period stipulated in the contract and the guarantee period stipulated in the preceding paragraph, the guarantor shall be exempted from the guarantee liability; If the creditor has filed a lawsuit or applied for arbitration, the limitation of action shall be interrupted during the guarantee period. In joint guarantee, if the creditor causes the guarantor to sign a guarantee contract against his will by fraud, coercion or other improper means, it can be considered as an invalid contract, and the guarantor does not have to bear the guarantee responsibility. In order to urge the creditor to exercise his rights, if the creditor fails to ask the guarantor to repay the loan six months after the maturity of the principal debt, the guarantor does not need to bear the guarantee responsibility.

Legal basis: The guarantor of the general guarantee in Article 698 of the Civil Code of People's Republic of China (PRC) provides the creditor with the real situation of the debtor's executable property after the expiration of the main debt performance period. If the creditor gives up or is slow to exercise his rights, and the property cannot be executed, the guarantor will no longer bear the guarantee responsibility within the range of the value of the executable property provided by him.
