How was Changsha, the tallest building in the world, the "City of the Sky" built? Has anyone seen it? Is it true?/You don't say. /You don't say.

You mean the Sky City of Broad Company, which is Roy Building. Yuanda Company claims to plan to build a skyscraper in Wangcheng District, Changsha City, Hunan Province, China. It is planned to build 838 meters, with 202 floors above ground and 6 floors underground, surpassing the Burj Khalifa to become the tallest building in the world. Because of its modular construction method, it is also called building block. The planned construction period is only 90 days. Some people say that there are only two kinds of architects like that, one is an unprecedented genius and the other is an ignorant liar. I haven't heard of any progress in this project at present.
