In the autumn harvest season, farmers in Jinnan area of the Loess Plateau used to pick walnuts and put them on the Xia slope (that is, the tile roof) to dry. After the walnut was dried, the wind blew down, rolled down with the waves, slammed and pingpong, and fell to the ground. Music simulates the sound of rolling walnuts on a downhill slope, and expresses farmers' joy in celebrating the harvest.
