Those are the best dancers at that age I have ever seen. Usually three and four-year-olds are distracted and running all over the place, or not moving, or crying and shuffling their feet… But these kids knew exactly what they were doing. The teachers who are in charge of these kids are doing a fantastic job! It did look like the kids were having fun. I hope they aren’t being run strictly in class. I can’t imagine how you would get a child to behave so well in a performance. But perhaps the teachers have progressive teaching techniques! Well done!
From other videos I have seen about China and their "training" methods, not very pleasant for the little ones and they are treated like adults instead of tiny children. Way too advanced for 4 year olds, and I worry about their bodies in the future. Look up gymnastic videos.
