1. Contact the insurance company immediately: commercial insurance should be purchased before the store opens to deal with unexpected losses. After the store is damaged, you should contact the insurance company as soon as possible, report the case to the insurance company, and provide relevant proof materials of the loss so as to get compensation as soon as possible.

2. Confirm the loss range: The store needs to confirm its loss range as soon as possible, including the lost items, value and the cost of maintenance and replacement. Shops can be evaluated by their own maintenance personnel or professionals arranged by insurance companies.

3. Communication with the management of the food city: Shops also need to communicate with the management of the food city to understand the property insurance situation of the food city and the compensation scheme for the damage of the shops by the management of the food city. Shops can solve the compensation problem through legal channels or negotiation.

4. Seek legal aid: If the compensation negotiation between the store and the management of the food city cannot reach an agreement, the store can seek legal aid and solve the compensation problem through legal channels.
