Paying a deposit is to book that product, and the deposit is a guarantee for the seller. It is a matter of good faith to run the bill without making up the final payment. If you really don't have the money to make up the balance or don't want it, you can resell the deposit to the idle fish. The behavior of the other party to the contract who has the obligation to pay the contract amount is a breach of contract and should bear the corresponding liability for breach of contract. According to the provisions of the Contract Law, if one party fails to perform the contractual obligations or fails to meet the contractual obligations, it shall be liable for breach of contract such as continuing to perform, taking remedial measures or compensating for losses.

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

If one party fails to pay the price or remuneration, the other party may require it to pay the price or remuneration.
