Tonight I asked my 4 year old daughter to 'make up a song' and I told her I'd keep quiet and simply listen to her. Surprisingly she improvised a short piece a few minutes long which included harmonics FanYin 泛音 and Gun 滚 Fu 拂 techniques (using finger to make circular motion on all 7 strings). Her fingers are still too tiny to slide on the guqin silk strings. Too much ropeburn from the silk strings, even for beginner adult players like me. Too painful. Haha. Playing guqin alone is too boring. I prefer to play with my daughters (if they also feel like playing. Haha. I don't force them).
