Is Shanghai dialect the Minnan dialect? The same? What is the difference?

Shanghai dialect is a unique dialect in Shanghai, which belongs to a small piece of Wu dialect in Taihu Lake. Suhujia is a kind of southern dialect. In contrast, some people call Cantonese as Cantonese, Taiwan Province Minnan dialect as Taiwanese, and some people call Shanghai dialect as Shanghai dialect (which is rare). Pronunciation was greatly influenced by Suzhou and Ningbo, which dominated the early immigrants. Pronunciation is similar to Ningbo dialect and Suzhou dialect. According to the latest textual research, Shanghai dialect is the result of the development of Songjiang dialect, and the synthesis of Suzhou dialect in Ningbo dialect can be regarded as some factors that have influenced this dialect, such as intonation. Songjiang dialect is the main vein of Shanghai dialect.

The 1930s was the golden age of Shanghai dialect. Similar to Hong Kong, writers in Shanghai freely translated or transliterated many English neologisms, which were used in written texts, spread through various developed print media in Shanghai at that time, and then absorbed by Mandarin. Since the late 1980s, all schools in Shanghai have taught in Putonghua. Many schools treat dialect speaking differently. In addition, the government canceled the Shanghai content in many radio and TV programs. The word-making ability of Shanghai dialect has also begun to decline seriously. Now Shanghai is still a Wu-speaking city, and Mandarin is also very common. With the increasing number of immigrants from all over China, the proportion of people who can speak Shanghainese began to decrease. Nowadays, it is difficult to recruit young Shanghai opera actors with qualified pronunciation. Since the 20th century, there has been a wave of "defending Shanghai dialect" in Shanghai.
