I haven't heard of it. Not so good. You don't have to choose such an expensive kindergarten. When there are so many children in a class, the teacher is always tired. If you quarrel with children or stare at them, it will seriously cause psychological shadows and psychological fears to children, which will have a serious impact on children's childhood. You might as well choose one or two early education institutions, one for one and one for group activities, which will be of great help to children. At the beginning, my baby enrolled in a one-on-one right brain development and group activity sensory integration class. I didn't know what it was for. Now it seems that children are much better than their peers. Especially one-on-one right brain development is the most helpful. Sensory training is also of great help to children's physical fitness.
