Shanghai's important historical position in modern history.

After the First Opium War, according to the Sino-British treaty of nanking signed in 1842, Shanghai became one of the five foreign trade ports in 1843, and Britain, the United States, France and other countries successively set up their posts in Shanghai. In the 25th year of Daoguang (1845), at the request of British Consul Pavel, Jianghai North Pass ("New Pass" and "Foreign Pass") was set up in the concession to handle the collection of customs duties from foreign ships, and Jiangsu Susongtai Road was also in charge. In the third year of Xianfeng (1853), the British took advantage of the knife uprising to seize the customs of Jiang. The following year, Wu signed an agreement with the British, French and American consuls in Shanghai, allowing each of the three countries to send a tax office to take charge of Jiang Customs. In July of the same year, Shaoguan Tax Management Committee was established, which set a bad example for foreign invaders to directly manage China Customs. During the Taiping Heavenly Kingdom War, 1855 Knife Club Liulichuan,160 June Taiping Army Lai and 1862 early Taiping Army Li Xiucheng fought three battles and occupied a part of Shanghai. 1854, Shanghai established the Ministry of Industry, an autonomous organization, and turned into a concession independent of the administrative jurisdiction of the Qing Dynasty. Since then, the two concessions in Shanghai have been managed separately from the local government in China: the southern areas along the Yangtze River in Huangpu, Jing 'an, Hongkou and Yangpu are mainly public concessions (mainly British and American); The core areas of Luwan District and Xuhui District are mainly French Concessions. Changning is a cross-border road construction area in the public concession; However, Zhabei and Heather, two areas managed by China (the Chinese border), were separated by concessions. After the opening of the port, Shanghai quickly became the most prosperous international metropolis in Asia, and was known as "Shili Yangchang", "Oriental Paris", "Oriental Magic Capital", "Adventurer's Paradise" and "First Financial Center in the Far East". The existence of the Concession made the core hinterland of Shanghai not affected by the war, enjoyed the actual independent status and full international ties, and laid the foundation for today's prosperity.
