1. The purpose of the contract cannot be achieved due to force majeure. If the purpose of the contract cannot be achieved due to force majeure, the contract will lose its meaning and should be eliminated.
2. Before the expiration of the performance period, one party clearly indicated or indicated by its own behavior that it would not perform the main debt. This means that the debtor refuses to perform, also known as breach of contract, including express breach of contract and implied breach of contract. As a condition for the termination of the contract, the debtor is required to be at fault, refuse the illegal act (unable to determine the cause) and have the ability to perform.
3. One party delays the performance of the principal debt and fails to perform it within a reasonable period after being urged. This is the debtor's delay in performance.
4. One party delays the performance of debts or commits other breach of contract, which makes it impossible to achieve the purpose of the contract. For some contracts, the time limit for performance is very important. If the debtor fails to perform on time, the purpose of the contract cannot be achieved. In this case, the creditor has the right to terminate the contract. The same should be true when other breach of contract leads to the failure of the contract purpose.
5. Other circumstances stipulated by law.
