If you have land, you can consider planting your own land and planting some wheat, corn and vegetables, which can not only meet the demand of self-sufficiency, but also ensure the quality and freshness of food. It's a good choice.
If there is no land, we might as well consider breeding, such as raising chickens, ducks and pigs. These creatures reproduce very quickly. As long as it is properly managed, making money is a good choice.
In addition, you can also consider opening your own small shop, such as a small supermarket or restaurant, and earning some extra money can also drive the local economic development.
Generally speaking, how to support yourself in rural life mainly depends on the local environment and resources. Although life is simple, it can also be beautiful.
