What does it mean to restrict all property rights in the property right nature column on the real estate license?

Houses sold through housing reform are all limited property rights, that is to say, houses used to be public houses by units or real estate management departments, and the land used for building houses is generally zoned out. 1993 the state implemented the housing reform policy, through which such houses were sold to employees or original tenants at low prices. Now, if you want to sell them again, you must pay part of the land transfer fee (or land income) to the government before you can sell them. Therefore, it is ok to handle the sale and transfer, but the premise is to pay the land transfer fee to the government department. This is called limited ownership.
