Fallen leaves, red leaves and yellow leaves are playing hide-and-seek children's songs. The background is that music education should be aesthetic education in essence. People can know themselves, know themselves and shape themselves through music. Similarly, music can provide a new dimension for children to know the world. This nursery rhyme, produced by Fibel Company, takes the lead in breaking the teaching methods of traditional music training institutions, adopts international advanced music education theory and practice, shifts the focus of music teaching objectives from "music" to "people", and emphasizes that "music education can cultivate a complete person", and develops individual intuition, thinking, imagination, expression and communication skills first, and then carries out technical training based on music literacy.
