1. First of all, big cities have higher incomes and better working conditions. Even ordinary people can get a satisfactory income by their own labor. Because of strict supervision and management in all aspects, the working environment in big cities is relatively better. 2. Because of the large population in big cities and the well-allocated resources in education, medical care, transportation and services, there are many companies, large and small. Regardless of gender, people with mild disabilities can easily find jobs that suit them and are likely to be promoted in the future. 3. Big cities are basically industrial clusters, and young people have relatively more employment opportunities in big cities. Especially for young people with high academic qualifications and strong ability, there are more development opportunities. Even if your education is average, as long as you have a skill, you will find it easy to make money in a big city. Back in the small mountain village, there is nothing I can do about my little specialty. It is very likely that you are an ordinary farmer. If you haven't found your own specialty yet, as long as you have the determination to take root in a big city, there are many choices in a big city for you to find yourself promising, so it's not difficult to stay in a big city. 4. Give children a better starting point. It is possible that you have struggled for most of your life, and it is only in middle age that you really integrate into the big city. By this time, you will find that your sons and grandchildren are enjoying everything you have brought them, especially those of us who were born in poor places. If we don't prepare some for our children, when they want to develop their lives in big cities in the future, whether they hate you or not, you will definitely not be happy at this time. For example, a relative of mine, with little education, developed in a big city and learned a good dish. He even bought two houses for his children in the provincial capital, and his life is booming. Many graduates from regular schools are not as good as him now. When they get home, everyone will take a high look at what they are doing. I hope I can help you.
