What's the difference between Shanghai's traditional culture and other places in China?

Just give me a rough idea. It is not enough to write a few specific books.

Shanghai is an immigrant city. According to treaty of nanking, since the opening of 1843, it has experienced several waves of immigrants from Suzhou, Ningbo and northern Jiangsu, and was once a concession for foreigners. 49 years later, immigrants from all over the country brought multiculturalism. Shanghai's so-called Shanghai culture is an inclusive culture, which is inclusive, pragmatic, efficient and open.

The traditional diet in Shanghai is a local dish with thick oil and red sauce, while the modern diet is relatively light. Some people may think that Shanghai food is sweeter because of the influence of Wuxi. Shanghainese also prefer ethnic and international cuisines, such as Sichuan cuisine and western food, which are very popular, so it is of little significance to define a Shanghai cuisine style.

Shanghai's customs and etiquette combine international standards with China's characteristics. There are both the characteristics of modern civilized society and some bad habits. This is caused by complicated reasons. For foreigners and China people, Shanghai is the least China city in China, so the comments are mixed. Fortunately, Shanghai culture is generally tolerant and confident, so it has not caused much trouble.
