The bottom center hole is called the GU sound. According to the Helmholtz principle, it can emit a very obvious sound resonance effect when tapping, and a series of connected harmonic columns are generated through the top Ding pitch. Purely hand-finished, using good quality steel with acoustic quality from the material selection, the phoneme has been carefully drawn and measured, and after numerous manual beatings, the tuning is step by step with precision instruments.
