The second reason is that the education level in big cities is much higher than that in county towns. Children of the same age live in different places, so they have different education and different knowledge. Children in big cities must have seen much more than children in small counties. Therefore, if you want to choose, you will definitely choose a big city.
Why do more and more people choose to work hard in big cities? Because they are not satisfied with their present living conditions, they want to live a better life and have more knowledge. If they can get a foothold in big cities in the future, they can undoubtedly give their children a better education. Some people, born in small counties and well-off, still choose to live in big cities and want to see more things. There are too many restrictions in small counties and the traffic is not as convenient as in big cities, so life in big cities is more modern. But everyone's choice is different. Some people like a slow-paced life, each with its own advantages.
