Is the property of Yujingyuan black? I don't see if I can buy a parking space.

Don't buy a parking space, and don't let owners without parking spaces park in the community, right? Whether the property is black or not can't be seen from the events you stated, but the basis of your idea is not very good. Owners without parking spaces should not enter the community by themselves. Why use things that have no right to use, and complain about the behavior of managers? This is no different from watching others eat abalone but can't afford it, and complaining in your heart that the other person doesn't choke to death.
