The way to let the wedding boss refund the deposit is as follows:
 1. If both parties agree on the return of the deposit in the contract, the agreement shall prevail;
 2. If there is no agreement, both parties can negotiate in advance and ask the wedding boss to return the deposit;
 3. If the agreement is not reached through consultation, if the purpose of the contract cannot be achieved due to the fault of the wedding boss, a lawsuit can be filed to the people's court to ask it to return double the deposit.
 [Legal Basis]
 Article 587 of the Civil Code states that if the debtor performs his obligation, the deposit shall be set off against the price or recovered. If the party who pays the deposit fails to perform its obligations or fails to perform its obligations in accordance with the agreement, which makes it impossible to achieve the purpose of the contract, it shall not have the right to request the return of the deposit; If the party receiving the deposit fails to perform its obligations or fails to perform its obligations in accordance with the agreement, which makes it impossible to achieve the purpose of the contract, it shall return twice the amount of the deposit.
