Shanghai is one of the most developed cities in China. Shanghai is at the leading level in China in terms of economy, culture and transportation facilities. Shanghai is one of the most important cities in China, because it has developed economy and occupies an important position in foreign exchanges. In the development of many people, Shanghai came into being and developed into modern times, that is, after the Qing Dynasty. However, Shanghai is actually a city with a long history of more than 3,000 years. As early as the Yao Dynasty, people lived here and established cities. It belonged to Yangzhou at that time. Moreover, this administrative title continued until the Spring and Autumn Period and the Warring States Period. Shanghai didn't change much in the Spring and Autumn Period, but it gained a title in the Warring States Period. At that time, the fiefs of the Four Childes of the Warring States and Chu Shen Jun were in the present Shanghai area. After Chun's fief was demarcated, Chun began to build a city in Shanghai, and the name of the city was Shencheng. Later, the location of Shencheng changed constantly, but it was all around Shanghai. For a long time, Shanghai has existed in Shenzhen as a city. During the Three Kingdoms period, the geographical location of Shencheng was indeed determined, but its name changed and it was renamed Huating. After the Tang Dynasty, it was designated as the county seat. At this moment, Shanghai really achieved its first development and became Huating County. Because the economic center of gravity at that time was always North China, Huating County, which was still a long way from North China, was not taken seriously. Although Huating county was also a port city at that time, there was no difference between port and non-port from the perspective of economic development model at that time. During the Yuan and Ming Dynasties, Shanghai achieved initial economic development, the economic center of gravity moved south, and many cities in the south were developed and developed. By the end of the Ming Dynasty, Yangzhou, Suzhou and other cities had developed into economic centers at that time. Under the radiation of these cities, Shanghai's economy has also developed initially. After the Qing Dynasty entered the customs, the northern economy was greatly damaged, and even Yangzhou developed slowly for political reasons, and Shanghai's development stagnated. However, with the Qing government's emphasis on China's economy, the whole country has witnessed a thriving recovery, and Shanghai is no exception. It developed steadily until the late Qing Dynasty, and its political status also rose with the development of economy. After the Opium War, the coastal cities of China were occupied by Britain, France, Germany and the United States as concessions at that time. As an important port city at that time, Shanghai failed to survive this disaster. Although the history of being occupied as a concession was humiliating, it promoted the development of Shanghai to some extent. /p
