What about a super high-rise building without 40 floors?

Continue to build. Super-high-rise building refers to a building with more than 40 floors and a height exceeding 100 meters. There is no 40 floors to continue construction. China's General Principles for Civil Building Design (GB50352—2005) stipulates that when the building height exceeds 100m, both residential buildings and public buildings are super high-rise buildings. According to the new standard of the World Society of Super Tall Buildings, buildings over 300 m are super tall buildings. In May 2020, the Ministry of Housing and Urban-Rural Development of China and the National Development and Reform Commission jointly issued a notice, requiring all localities to further strengthen the management of urban and architectural features and strictly restrict them.
