How to make children become programming experts easily

At present, there is a lack of programming education for children and teenagers in China, and primary and secondary schools have basically become entry-level Office training. This not only hinders children's understanding of computers, but also contributes to children's lack of interest in computers. Last year, my son and I tried to learn computer programming with the Scratch programming platform provided by MIT. This is a computer science popularization project for the world. Both the community and the software are free and available in multiple languages.
