Nanjing culture is a cultural circle centered on Nanjing, China's four ancient capitals and a famous national historical and cultural city, and radiating to the surrounding areas. It is an important part of Han civilization. Nanjing has long been the political, economic, cultural and educational center of southern China. Nanjing culture is formed on the basis of the integration of the mainstream culture of the Central Plains and the southern culture of Guan Yi Nandu. Its leading feature is the intersection of North and South, inclusiveness and openness, which is unique. 1 Nanjing culture is characterized by the coexistence and mutual integration of Nanjing Mandarin and Wu dialect. Historically, China's three southern tours combined the North and South cultures, and Nanjing culture also absorbed the mainstream culture of the Central Plains, forming a unique cultural region; Geographically, the cultural origin of Nanjing has obvious characteristics of Jiangnan culture and Wu culture, and has absorbed the exquisite market of Jiangnan culture. Nanjing culture mainly includes the culture of the Six Dynasties, the culture of the Ming Dynasty and the culture of the Republic of China, all of which can be attributed to the "capital culture". The mainstream capital culture does not exclude other cultures, such as Qinhuai culture in its heyday, which not only embodies the red powder culture and market customs, but also contains national integrity and patriotism. 1 Since ancient times, "the wealth of the world, out of the southeast, Jinling is its club", Nanjing is also the capital of the ten dynasties. "The cultural relics in the clothes are rich in southeast and urban atmosphere, with profound cultural connotations, showing a bit of elegance, heroic, gentle and beautiful, and rich and harmonious." At the same time, Nanjing, as the hub of world literature, has a profound cultural heritage. The so-called "food maid bartenders also had smoke and water in the Six Dynasties".
