Although it is convenient to buy a lot of things online even in rural areas, humanistic atmosphere can't be bought. In a small county, because the place is small, big shopping malls and big libraries can't survive. Even if children want to learn dance, they have to go to bigger places. They have solved the housing problem in big cities and should stick to it.
Life in a small county is very comfortable, but everyone's life pressure is not great. They have no more entertainment and consumption activities. They watch TV, play cards, drink and chat all day after work, but the content of chatting can't escape the trivial things of daily life. When they really want to see the world, they still have a lot of concerns.
However, if you go back to the county to do business, it is easier to make money there, and you don't have to sell the house in Chengdu. You can rent a house in a small county. Chengdu can be used as a strategic rear area, and it needs some network resources to do business. You can also go back to Chengdu to inspect the market during the holiday. However, these are only personal opinions, and all decisions should be combined with their own circumstances.
