Shanghai Hongkou tax is not reported because Shanghai's housing prices are relatively high, and most people can't afford it. Shanghai Taxation Bureau is suitable for people with well-off families, because in addition to the cost of living such as renting a house, you should also consider getting married and buying a house in the future. But look at the housing prices and wages in Shanghai, so the cost performance is extremely low, which is not as good as that of institutions in Jiangsu and Zhejiang, so the number of applicants is relatively small. On the contrary, the number of applicants in some second-and third-tier cities has skyrocketed.
