Guqin, also known as Yaoqin, Yuqin, Sitong and Qixianqin, is a traditional plucked string instrument of the Han nationality in China. It has a history of more than 3,000 years and belongs to the silk among the eight musical instruments. Guqin has a wide range of sound, deep timbre and long lingering sound. Since ancient times, "qin" has been a special reference to it. In the 1920s, it was renamed Guqin to distinguish it from the piano. In ancient times, it had five strings, and in the Western Zhou Dynasty, it was set as seven strings, and there were 13 emblems to mark the musical scale. It was a ritual instrument and a standard instrument for musical scale. Qin is the most noble musical instrument in Han culture. There are sayings such as "a scholar does not put away the qin without reason" and "the left qin and the right book". It ranks first among the four arts of Chinese traditional culture, "qin, chess, calligraphy and painting". Guqin making skills are an intangible cultural heritage project at the Fangshan District level. The inheritor of the project, Kong Dehui, whose name is Yufeng and his nickname is Yaoqin Shizhe, was born in Beijing, with his ancestral home in Qufu, Shandong. He is the 77th generation grandson of Confucius and the third generation inheritor of Jiuyi School. In 2005, he first learned to play Guqin with teacher Sun Zhi at Hongxianqin Museum. In 2010, he began to learn the art of making guqin from Mr. Tian Shuangkun and tried to make two guqins. In 2011, he founded the "Taihe Qinfang" studio and began to systematically study the art of making guqin. In 2015, a ceremony for apprenticeship in the art of making guqin was held at the "Yutian Qinzhai", and Mr. Tian Shuangkun, a famous guqin maker of the Jiuyi School, was formally worshipped as his teacher. Kong Dehui is now mainly committed to the study of guqin making. Guqin is made purely by hand, including ten major processes: material selection, shaping, groove belly, guqin assembly, ash base, grinding, polishing, fixing the pegs, installing the feet, and stringing. For thousands of years, among many musical instruments, the guqin has become an important yardstick for measuring the cultivation of ancient literati with its rich intrinsic cultural value. The rich intrinsic cultural value of the guqin can be simply summarized as the high degree of integration of life art and art life, which also helps art prolong its existence cycle in real life.
