I bought a parking space for civil air defense, but will I recover it if I change my property rights?

According to the regulations, civil air defense parking spaces cannot be sold, so owners who have already purchased civil air defense parking spaces can negotiate with developers and ask them to refund compensation or re-sign a parking space purchase agreement to purchase property parking spaces. According to relevant regulations, civil air defense parking spaces refer to parking spaces occupying the construction area of civil air defense projects and belong to national defense assets. If you buy a property parking space, you will be given proof of ownership. No matter how many properties you change, this parking space belongs to you. There are two main types of parking spaces, one is the property parking space, which can apply for the certificate of immovable property rights, and the other is the parking space with the right to use, which cannot apply for the certificate of immovable property rights. You must buy a parking space with property rights. If it is a parking space with the right to use, the owner only has the right to use, but has no ownership, which will affect the appreciation of the parking space and will be restricted in the future.
