Will Northeasters go to Shanghai and not adapt to the climate there?

Northeasters who are new here are generally not used to it. They think Shanghai is too humid, there are many cars and people, and the air is not good. Some people will be acclimatized (my classmates in Harbin have acne, some have irregular menstruation or other symptoms). If you are not acclimatized, you'd better go to a good hospital. Most people will recover in a month or so. It doesn't matter. Snacks in Shanghai are generally sweet, while Shanghai food is salty and sweet, and most people in Northeast China are not used to it. Shanghai is foggy, and it is wet, cold and without heating in winter. Although the body is not cold, my head is exposed and my head is frozen. The zero degree in Shanghai is similar to the cold degree of MINUS 6 or 7 degrees in the north, because Shanghai is wetter than the north. The temperature in Shanghai is high in summer and it enters the rainy season in June. Under normal circumstances, it rains every day. It often rains in autumn and spring, but it is much softer than summer rain. After staying in Shanghai for several years, I may not adapt to the dryness in the north. The humidity in Shanghai is moist and good for women's skin.
