Why do Shanghainese like Ningbo people and Suzhou people?

Let me answer this question. Ningbo people and Suzhou people are the first immigrants from the south of the Yangtze River who went to Shanghai since the opening of Shanghai, and they have made indelible contributions to the development of Greater Shanghai. Besides, Ningbo people and Suzhou people, like Shanghainese, belong to Wu dialect, and Shanghainese are very kind to them. Nowadays, many words in Shanghai dialect come from Ningbo dialect and Suzhou dialect.
