The idea of happy education is to emphasize children's subjectivity and autonomy, take children's natural needs as the starting point, and help children learn and develop independently through guidance and inspiration. Happy education not only pays attention to imparting knowledge, but also pays attention to cultivating children's creativity, innovative thinking, emotional attitude and other abilities. Therefore, happy education is not to teach nothing, but to achieve the purpose of education by creating a positive learning atmosphere and cultivating the ability of autonomous learning. From the perspective of education, happy education emphasizes cultivating children's all-round development, respecting children's self-awareness and needs, and encouraging children to explore and create independently. This kind of education can stimulate children's interest in learning, enhance their learning motivation and contribute to their growth and development.
