Why does Shanghai fascinate many Japanese and settle down?

I'm afraid this problem should be discussed from the perspective of food culture.

Let me start with the geographical location of Shanghai. Among the coastal and domestic developed cities, the economy is developed and the conditions are superior. Her geographical position makes it very convenient to fly to Japan. My teacher stayed in Japan for ten years, and she said that she had transferred from Shanghai before. So if the geographical location is convenient, naturally the Japanese are willing to go.

Another important point is naturally diet. How can you live if you are not used to eating? After all, food is the first thing for people, right? Shanghainese prefer sweets, and most Shanghai dishes are not spicy, which is more in line with Japanese tastes. For example, none of the Kanto dishes we eat in China will be authentic, because Japanese Kanto dishes are sweet and hardly spicy. My foreign teachers think that hot and sour shredded potatoes are more acceptable to them, so this shows that.
