What should I do if I signed a canteen contract with the site property and was returned by the project?

Unilateral termination of the contract belongs to unilateral breach of contract. But this kind of contract is generally not applicable to compulsory performance, so it is necessary to pay liquidated damages.

Article 108 If a party expressly expresses or shows by his own behavior that he will not perform his contractual obligations, the other party may require him to bear the liability for breach of contract before the expiration of the performance period.

Article 110 If one party fails to perform the non-monetary debt or the performance of the non-monetary debt does not conform to the agreement, the other party may demand performance, except in any of the following circumstances:

(1) It cannot be performed legally or in fact.

(two) the subject matter of the debt is not suitable for compulsory performance or the cost of performance is too high.

(3) The creditor fails to demand performance within a reasonable time limit.
