The music Feiqu represents the wisdom of the ancients.

Because the ancient spring in the lyrics of "Flying Sky" refers to the Crescent Moon Spring, and the rainbow in the desert refers to the Mogao Grottoes. Representing the wisdom of the ancients, the Mogao Grottoes are like a rainbow. Therefore, the music Feiqu represents the wisdom of the ancients.

The tone of Feiqu is high-pitched, bold, unrestrained, and bright. When it is sung, the sound shakes the valley and has a strong appeal.
