hehe, it's this program.
you should first make a feasibility study report of a project, or a project proposal, and entrust it to a professional consulting organization. After that, an application is submitted to the National Development and Reform Commission for approval of this report. The document approved by the National Development and Reform Commission is called the approval of the project, that is, the approval to implement the project, or the approval of the feasibility study report. This is the legal approval document for your project. You can ask the NDRC department in detail. Generally, the investment department manages this matter, and they will give you a hint. The practices in different places are not consistent.
I hope I can help you.
