This song was composed by Zhao Songting. The music describes the life of the sun rising from the east on a spring morning, birds singing in the trees, and children playing happily in the forest.
The first paragraph describes a quiet and beautiful morning when the sun slowly rises and shines on the forest, and the birds open their sleepy eyes and stretch their wings.
In the second paragraph, the forest comes alive, the birds sing happily, you sing me and you call me, there are far and near, the birds contend, the flowers bloom, it is a fresh and cheerful morning.
In the third section, the children dance in the beautiful forest, accompanied by birds. From the "extremely fast" point, is the climax of the dance, and then gradually quiet.
The end is a morning reminiscent of spring.
