Does the property company have the right to sell green land?

Land is the land of the country, no one has the right to buy or sell, and the land use right of the community belongs to all owners. Property is just a service company. Where do you get the right to dispose of everyone's property?

Greening is greening and cannot change the nature of use. If you are the owner, you can collect evidence, demand the return, or expel the current property.
