Why is the attraction of Beijing-Tianjin-Hebei declining in recent years? On the one hand, there is only one core city in Beijing, but Beijing alone cannot drive the development of all cities. After all, Beijing's economy, education, medical care and other aspects are higher than those of surrounding cities, which leads to the transfer of most of the northern drift to Beijing, and the attractiveness of surrounding cities will decline, so the population growth here will decline year by year.

These cities are closely linked and developing rapidly, and now they have become the first choice for many young people to work and live. Not to mention urban agglomerations such as the Yangtze River Delta and the Pearl River Delta, urban agglomerations formed by new first-tier cities such as Chengdu and Changsha are now the first choice for many young people.

Although compared with many traditional first-tier cities, the new first-tier cities may not be very high in all aspects, but today's development is also very good, especially compared with cities like Beijing, Guangzhou and Shenzhen, the pressure of life and work is much lower.

In some places, the settlement policy is ".
