Nan huaijin's personal fortune-telling _ nan huaijin's fortune-telling

Who is Professor Sun, the master of Chinese music mentioned by Mr. Nan in Zhuangzi?

Sun Wenming, a China folk music erhu player, was born in Shangyu, Zhejiang. Later, due to the adoption of the Pan family, it was renamed Pan. 1928 Sun Wenming was born in a peasant family in Xia Yutang village, Shangyu. His father was a tailor first, and then a native countryman. When Sun Wenming was four years old, he was blind from smallpox. When he was twelve years old, he studied erhu with his uncle, Taoist Ding. At the end of the same year, his mother Sun Dafeng died and his father married his stepmother. So the next year, Sun Wenming and his brother left their hometown, wandering in northern Zhejiang and southern Jiangsu, and began to learn fortune telling to make a living. Because he hated his father's indifference to his two brothers, Sun Wenming has been using his mother's surname since he left home.
