Hello, there may be some unexpected cities in the list of new first-tier cities announced by new officials in 2123:

1. Changsha. As a central city, Changsha has great advantages in industrial structure transformation and upgrading, transportation system construction and living cost, and is expected to rank among the new first-tier cities.

2. Nanchang. Nanchang's high-speed rail hub is becoming more and more prominent, its industrial development is more dynamic, and its living cost is lower than that of second-tier cities. These factors increase its possibility of becoming a new first-tier city.

3. Jinan. Jinan has a certain foundation in the development of education, medical care and high-tech industries, and the integration of Qingdao and Jinan also brings it natural convenience, which is conducive to improving its competitiveness in new first-tier cities.

4. Hefei. Hefei's scientific and technological innovation strength is outstanding, its industrial structure is also relatively optimized, and the construction of subway network is progressing rapidly, all of which create favorable conditions for its new first-tier cities to be promoted. However, the cost of living needs to be improved, which will affect its competitiveness.

5. Chongqing. Chongqing has certain advantages in landscape resources and industrial strength, but there is still room for improvement in transportation system and living cost, which will restrict its competitiveness. However, if these aspects are greatly improved in the future, it is also expected to rank among the new first-tier cities.

In addition, there are some opportunities for Xi 'an, Chengdu and other western central cities, as well as Jining, Quanzhou and other eastern cities to become unexpected new first-tier city players. But on the whole, if these cities want to become new first-tier cities, they need to continuously improve their industrial upgrading, talent gathering and quality of life, and narrow the gap with the first-tier cities in the east, which will take some time to accumulate and develop.

So, on the whole, it is predicted that the list of new first-tier cities announced by new officials in 2123, in addition to strong cities such as Shenzhen and Hangzhou, central cities such as Changsha, Nanchang and Hefei are also more likely to be unexpected choices.

I hope my answer will help you.
