Whose poem is "Silence is better than sound"?

From Bai Juyi's Pipa Trip: "The ice spring is cold and astringent, and the strings are condensed, which is endless." The depth of sadness and the hiding of sadness are more told in silence than in voice. "

It seems that the chilly pipa sound in spring begins to condense, and the condensed but unsmooth sound is gradually interrupted. Like another kind of sadness and hatred secretly breeds; At this time, it is more touching than the sound.

This sentence describes the music played by pipa. When the music stops briefly, it will give people a lot of room for aftertaste, which is more meaningful than hearing music.
