Legal analysis: it depends on the reason. After the establishment of the contract, the objective situation has changed significantly, which is not a commercial risk and cannot be foreseen by the parties when concluding the contract. If one party continues to perform the contract or fails to achieve the purpose of the contract, and the party requests the people's court to modify or terminate the contract, the people's court shall decide whether to modify or terminate the contract according to the principle of fairness and the actual situation of the case.
