Can be applied to every child. But it depends on how to use it, whether it is used at the right time, and don't use it blindly. I think one or two methods are not enough for children's education. Appreciation education and frustration education should be used at the same time, and both are indispensable. Make sure when it's time to make sure. If you do something wrong, you must face it mercilessly. Dare to face and take responsibility is what many children lack now.
