Gu Yanxian had a good piano skill all his life, and his family often put it on the spiritual bed. Zhang cried bitterly, so he went to bed, played the piano and played some songs. He said: "Gu Yanxian, this is quite rewarding?" Because he was very scared, he went out without holding the hand of his dutiful son.

Translation;

Gu Yanxian loved guqin very much when he was alive, and his family often put it on the coffin bed when he died. Zhang went to mourn, so sad that he couldn't help himself. He went straight to the cemetery to play the piano and played a few songs. After playing, he stroked the piano and said, "Gu Yanxian, can you still enjoy the sound of the piano?" With that, he burst into tears and went out without shaking hands with his son.
