In 1 1 year (1922), Sun Yat-sen pointed out: "If Shanghai remains unchanged, it will not meet the needs and requirements of becoming a world commercial port in the future." Then put forward "setting the world port in Shanghai". Shanghai Special Municipal Government, established in July 2006, followed Sun Yat-sen's policy and sought the development of its own jurisdiction, and put forward several draft urban construction plans. According to Dr. Sun Yat-sen's Outline for the Founding of the People's Republic of China, the Shanghai Special Municipal Government adopted the Great Shanghai Plan at its 23rd meeting in July 1929, which divided the flat Jiangwan area (about 7,000 mu, 460 hectares of land) bordering the new commercial port in the north, the concession in the south and the Huangpu River in the east into the central city. The project of this scheme started construction in the first half of 1930, and a series of roads were built in a farmland. With the new government building as the center, stadiums, libraries, museums, municipal hospitals, health laboratories, National Conservatory of Music, radio stations, China Aviation Association and other buildings have been built. A few years later, Lu Xu built an incredible new city in Shanghai, far from another city center in the concession.
