Yuan truly carried on national music traditions and has persisted in disseminating them. Yuan is from Yueyang, Hunan Province. Her love of music was not influenced by her family, unlike other performers of national instrumental music. Yuan’s father is an engineer and her mother a nurse. Her desire to perform and study national music was fostered by the vigorous and grand scene she witnessed of performers beating waist drums to celebrate the founding of New China.展开更多
