If the price of parking space soars, will the developer take back your parking space? If it is a legal contract for buying and selling parking spaces, there is basically no way out after the contract is fulfilled. If there are a large number of people, perhaps we can jointly put up slogans such as "unscrupulous merchants" and "black-hearted developers" in order to help the government coordinate. But this risk is also great, so be careful to violate the crime of disturbing social order.
