What should I do if the parking space in the community is always occupied?

Yes, you can. Some residential owners "opened up" parking spaces in the shade of public roads and green belts, and even installed ground locks and simple parking sheds, which not only changed the original land use functions such as transportation and greening, but also changed "all" into "private", resulting in other owners losing the opportunity of actual use and obviously infringing on the rights of other owners.
