I didn't have a copy of the real estate license when I installed the elevator. I just signed a copy of my ID card, okay?

You can't. According to the national elevator safety management measures, as of July 24, 2023, two copies of the real estate license and two copies of the ID card are required to install the elevator, so there is no copy of the real estate license to install the elevator, only the ID card is signed, so it is not allowed. Adding elevators requires a certain amount of capital investment. In addition to government subsidies and provident funds, it is also essential for low-level users and high-level users to share costs.
