Is the parking space on the sidewalk of Xiangcheng South Street free?

There is a notice board for paying parking spaces.

First of all, the toll collector should inform the charging unit whether it is a unit or an individual act. Since there is a charge, there should be a license document for the charge. If there is no charge, it is arbitrary charges. Roadside parking spaces belong to public parking spaces and should be free. I think it should be the local personal behavior or the personal behavior of the property company. In this case, I think if you report it, you should report it to the price bureau and the industrial and commercial bureau. Because I think it involves two levels: first, operating without permission. The second is to charge privately.
