I have a friend who lived in Shanghai for some time. She said that in Shanghai, if you don't wear those brands and drink afternoon tea, she feels sorry for the luxury of the city, so a lot of salary is spent on it. Of course, the rent is also very expensive, so although her salary is quite high, after one month, if you spend a little here and a little there, there will be little left.
Also, she said that the food in Shanghai is also very expensive, and it is small and exquisite, and the weight of things is not much, but it is scary, whether it is snacks or that kind of big meal. In addition, some daily consumption is also quite high, such as daily necessities, shopping in supermarkets, basically costing hundreds. So she basically doesn't eat out, and basically buys food and cooks by herself.
Of course, the consumption level in Beijing is also high. After all, it is a populous capital, and the rent is quite high. But I think it may be that northerners don't pay so much attention to these extra luxuries as southerners do, and northerners will be more practical, so I think the consumption level in Shanghai is relatively higher than that in Beijing.
