Guqin art is a solo art form of a horizontally placed stringed instrument. It also includes singing and playing qin songs and qin and flute ensembles. Guqin is also known as "qin", "seven-stringed qin", "green qin" and "silk tong". Guqin is said to have been created in the prehistoric legendary era of Fuxi and Shennong. Archaeological excavation data confirm that the shape of Guqin as a musical instrument had been fully developed by the Han Dynasty at the latest. Its performance art and style have been continuously improved through the creation of generations of qin players and literati. Guqin performance is the oldest instrumental performance form in Chinese history, with the highest artistic level, the most national spirit, aesthetic taste and traditional art characteristics. Guqin art is the second Chinese cultural category listed in the "Oral and Intangible Heritage of Humanity" after Kunqu Opera. Qin, chess, calligraphy and painting were once the four skills that ancient Chinese literati were proud of, and they were also four arts. Among them, Qin music is the most ancient and continuous instrumental music form in Chinese history, with a verifiable history of three thousand years. Idioms known to everyone, such as "High Mountain and Flowing Water", "Burning the Qin to Cook the Crane", and "Playing the Qin to a Cow", all come from stories related to the Qin. However, since the Qin has always been a kind of self-cultivation hobby for scholars and is rarely played in public, modern people's understanding of it is very limited.
