Why is Shanghai culture called "Shanghai culture"?

Baidu first introduces what is Shanghai culture:

Shanghai culture is a regional culture rooted in China traditional culture, which combines the essence of other regional cultures in China, such as Wuyue culture, and absorbs and digests some foreign cultural factors, mainly western cultural factors. "Koehler" is a transliteration of the English word "Colour", which also has the derivative meaning of classic. The earliest "Lao Keller" who absorbed the combination of Chinese and Western cultures and the combination of native and foreign cultures formed the early "Shanghai culture". 2 1 century, the young "Little Koehler" inherited the essence of Shanghai culture.

The culture of a place is closely related to its location, and Shanghai is now the economic, financial, trade, shipping and technological innovation center of China. Mainly because of its superior geographical location.

In 1930s, Shanghai was full of luxury goods and foreign cultures poured in. The wife in cheongsam is going to a foreign firm to pick up the goods. Ladies study English in missionary schools, celebrities dance in Yue Xian ballroom, and the decadent music in Paramount nightclub is the transition between old Shanghai and new Shanghai, and a blend of Chinese and western cultures.

Shanghai-style culture is characterized by eclecticism and being good at sublation.

This was achieved in Shanghai in the 1930s.
