1. Let them see the world more.
The frog in the well just sits in the same place. He never wants to jump out of this place to see what has changed in the world, so many times they just think that the sky in their eyes is that big, and he will think that the whole sky is only that big. It is because of their thoughts that their thoughts are imprisoned. Therefore, if we want to eliminate backward ideas, we can only let them accept more things and show them what the world is like. Naturally, they will change their minds. After all, if they watch too much, they will feel that their thoughts are too old-fashioned and they are exposed to too many things. Then in the process of talking with others, we can obviously feel that his thoughts have changed.
2. Develop some backward areas.
In fact, the best way is to develop these relatively backward areas and let more people see this area. So for people in this area, even if they don't leave this area, they can accept many things, because many people will come to this place, so people who come to this place will pass on their ideas, and cultural exchanges will produce more things, so they will gradually change their ideas. After all, when others are different from them, they will be too curious, want to learn and want to give others good things.
It is not culture but people who lag behind, because they are unwilling to touch new things and they will not change their minds. Therefore, only by pulling them out of this area and letting them accept more things can they change their minds.
