Although happy education pays attention to children's mental health and happiness, it does not mean that high-quality children can be taught. High-quality children should not only have mental health, but also have good knowledge and skills, which can adapt to the needs of society and make contributions to society. Happy education can provide a good psychological environment for children's growth, but to teach high-quality children, it is necessary to establish a good learning environment and provide rich knowledge and skills for children to grow up in practice.
