“…… Guqin master Bo Ya was playing the instrument in the wilderness, and the woodman Zhong Ziqi understood that his music was describing the “high mountains and flowing water.” Bo Ya was surprised, and said, “my heart echoes in yours,” They became very good friends, and when Ziqi was dead later, Bo Ya was devastated of losing the one who can really understand what was in his mind by listening to his music. He broke the instrument, and never played again in his life. The Chinese word Zhi Yin (confidant), literally meaning knowing the voice, also originated from this story.”
