My 4 year old daughter doing 滚拂 on guqin

My 4 year old daughter enjoys doing GunFu 滚拂 (running her fingers back and forth in circular motions across all 7 strings) on the silk strings mounted on my banana leaf shaped guqin. She does not know how to play any tunes yet. This is just to let her have fun and get her hands used to the rougher texture of silk strings. Ironic I know. Silk strings are rougher in texture than metal-nylon strings. Haha
