"You have no heart when playing the flute." This was the most outrageous thing Yan Qian Fu Ji ever said to me.
In order to retaliate against him, I chased him playing the flute for a whole day. Whenever he stopped, my butterflies would catch up and persecute him.
Decades later, when the young master grew up, the musicians could not only play the flute but also other things.
