Introduction to Linglun's pronunciation: Linglun was a music official in the Huangdi era and the ancestor of music making. The round carving is made from the bamboo of Ling Lun's Xi Valley, simulating the chirping of phoenix birds in nature, and creating the story of the musical instrument. The half-kneeling shape symbolizes Ling Lun's display of his musical achievements to the Yellow Emperor. The reliefs reflect scenes of ancient ancestors performing music and dance activities after their production and life after Linglun coined the pronunciation.
