Introduction to the foundation laying of Chaotianmen Square: At the end of the 20th century, with the opening of Chongqing to the outside world, the commissioning of the Three Gorges Project and the direct administration of Chongqing, Chongqing has attracted more and more attention from the outside world. The broken walls of Chaotianmen also gradually attracted the attention of Chongqing, so on March 28, 1998, in order to restore the glory of Chaotianmen, the municipal committee held a groundbreaking ceremony for the Chaotianmen Square construction project. On December 31 of the same year, Chaotianmen was officially opened to tourists.
