It's hard to say whether it will depreciate, but it's definitely impossible not to recycle it. Article 10 of the first chapter of the Constitution stipulates that "urban land belongs to the state. Land in rural areas and suburban areas belongs to the collective, except that it is owned by the state according to the law; Homestead, private plots and private hills are also collectively owned. The state may requisition land in accordance with the law for the needs of public interests. No organization or individual may occupy, buy, sell, lease or illegally transfer land in other forms. All organizations and individuals that use land must use land reasonably. " It is difficult to amend the constitution. As far as economic development is concerned, it is impossible not to recycle it. Urban planning will inevitably involve land recovery, so forget it.
