I woke up in Wuwu Mountain at the junction of Beiyun and Nanyin. As soon as I woke up, I was on the master's piano case. The master told me that it was the spirit of Si Ling, one of the ten famous qin's six hundred years ago, so I called Si Ling. But from the day I transformed, Si Ling It never played again because no one could play it. I stayed in Wushan for another twenty years. Finally, my master allowed me to go down the mountain. That day, under a clear sky, I took a few coins that I had never seen before and walked on the road to let myself play.
