XU Li-sun was born in 1897 in Nantong, Jiangsu province and passed away in 1969. When he was a student in Nanjing, he learned the qin from WANG Yan-qing of the Shandong Zhu Cheng School in 1917. And also learned the pipa from SHEN Zhao-zhou for the Ancient Tunes of Yingzhou. In 1929, he founded the Mei An Qin Society together with his schoolmate SHAO Da-su. And in 1931, he edited the Mei An Qin Scores according to the manscript of the Long Yin Guan Scores by his late qin teacher WANG Yan-qing. In 1936, he collected all the pipa scores learned from SHEN Zhao-zhou to form the Mei An Pipa Scores. Their studying place was called Mei An, which was by the side of the Six-Dynasty pine tree in their school, so they further extended the Zhu Cheng School to newly create a Mei An School in qin music. XU Li-sun has composed the Moon on Parasol Tree, Spring of the People’s Commune, etc. on qin music.
