Happy education refers to the educational goal of happy growth and all-round development by creating a harmonious and happy learning environment, taking students as the center, paying attention to giving full play to students' subjective initiative, cultivating students' interest and ability, and making students' intelligence, physical strength, aesthetic feeling, moral character and practice develop in an all-round way. The concept of happy education is completely different from traditional education. It emphasizes that students should learn and grow in a relaxed and pleasant atmosphere, respect students' individualized development, diversity of thinking modes and enthusiasm for learning, and emphasize equal interaction and cooperation between teachers and students in the process of education and teaching. Happy education is not to teach nothing and let nature take its course. We can understand happy education as a way of education, and adopt an entertaining way to make the learning process interesting, beneficial and meaningful. The content of happy education is planned and purposeful, but it is only taught in a way that children are interested in and willing to accept. The key of happy education is not to instill knowledge into students, but to guide children to actively study and explore under the drive of interest, and to stimulate children's learning interest and creativity. Under the background of "happy education", teachers are no longer "authorities" in the traditional sense, but "guides", respecting students' ideas and opinions in the teaching process and allowing students to participate in the education process. Happy education believes that students' participatory learning style can stimulate students' interest, let them better absorb knowledge and deepen it in practice. At the same time, happiness education also emphasizes the cultivation of students' emotions, making students feel happy, balanced, confident and brave. Therefore, happy education not only pays attention to students' academic performance, but also pays attention to their all-round development. In a word, happy education is not just let nature take its course, but based on children's cognitive characteristics and development laws, it guides children's active learning and development through entertaining and pursuing students' all-round development in many aspects. The purpose of happiness education is not to be happy, but to mold excellent personality and cultivate comprehensive quality in joy and happiness.
