China is the country with the largest number of elderly people and the fastest growth rate in the world. In the next few decades, the pressure of "population aging" will become one of the important factors that plague China's social development. Therefore, it will be "prioritized." The social old-age service is written into the 12th Five-Year Plan, which shows that the state attaches importance to the old-age care. The multi-storey houses (5~9 floors) built in China in the 1980s and 1990s, because of the lack of elevators, make the vertical traffic problem of multi-storey houses the most critical problem that plagues the elderly in the city. Older people often sit on the building. Governments at all levels are also trying hard to find ways to solve this problem, especially in Guangzhou, Shanghai, Beijing and other places to pilot the installation of box elevators in old multi-storey residential buildings, but found in the process of the pilot, old and multi-layer There are differences in the approval procedures, the unreasonable land area occupied by the hoistway, the high construction cost, the uneven benefits of low-rise households, and the impact on the lighting and ventilation of low-rise households.
