into four sections: City center plan: Comprising 1,000mu (~ 0.66km2) and shaped like the stylized Chinese character zhong (中) meaning "centre", this area would contain government buildings each with its own exercise area. There would also have been a museum, a library, a hospital and a sports stadium suitable for staging national events. A railway line connecting the city centre with a port on the Huangpu River and a railway line with goods depot near modern-day Qiujiang Road (). Division of the city into zones with the central area surrounded by industrial and residential areas. Traffic system: A grid of high speed roads leading out from the central government buildings in the centre to the west and south with a web of interconnected roads to the north and east. Construction of Zhongshan North (中山北路) and Zhongshan West Road (中山西路) leading to the southern downtown area and Qimei Road (其美路), modern day Siping Road, (四平路) and Huangxing Road (黄兴路) connecting to the International Settlement in the north west. A further 23 roads leading to Pudong, Jiangqiao and other local areas. Implementation Funding Once implementation of the plan began, the Nationalist Government issued bonds to cover the necessary construction funds. In 1929 they floated the First Phase Municipal Bond to raise 3,000,000 Chinese yuan based on marketable land values of between 200 and 600 yuan per Chinese acre. A land tax was further levied on the 5,400 mu that made up the proposed city centre area. Outside of this area, a surplus 829 mu of land was divided into two grades and sold for 2,500 yuan and 2,000 yuan per mu respectively, generating a profit of 1,795,560 yuan. New city hall The 1,000 mu site earmarked for the new Shanghai City Hall lay at the centre of the planned city. On 1October 1929 a design competition for the new building was launched with a prize of 3,000 yuan. The government announced architect Dong Dayou (董大酉) as the winner in February 1930 while further amendments were made to the overall plan. Work officially began on the site in June 1931 and was scheduled for completion the following year. However, Chinese nationalist forces clashed with the Japanese army in the January 28 Incident as Shanghai came under attack and the area between the Wujiaochang District (the modern day Yangpu District) and the Huangpu River, at the heart of the construction project, became a battlefield.
