Why do you always feel that Shanghainese are not good?

Shanghai is an immigrant city, and the proportion of Shanghainese in Shanghai's total population is very small. Especially after the reform and opening-up, millions of new immigrants from all levels poured into Shanghai. In essence, Shanghainese have no reason to be excluded, because Shanghainese are also mainlanders, and the difference is only the length of time in Shanghai. The economic and cultural differences between mainlanders, especially rural people, and Shanghainese are great. Just as Shanghainese always feel that there are many things they can't understand when they come to Hong Kong, how foreigners integrate with Shanghai is a conceptual problem. We should adjust our mentality, don't have the idea of inferiority, and don't have preconceptions about Shanghai. There are all kinds of people in Shanghai, with great differences in quality, but Shanghainese are very practical and look down on some people who think they are at a lower level.
