The classic listening and reading machine is a China classic listening and reading machine (story machine) jointly developed by Er Shen Science and Technology and China Education Research Association, which is used for early education and prenatal education. I bought it three years ago. At that time, only Er Shen and story machine were on the market. Later, many products came out, but Er Shen's was still better. After all, it is specially designed for this purpose, and it has been improving and has more experience.
