This brand describes Bai Juyi listening to the pipa on Xunyang River. Bai Juyi was banished to a secluded place at that time, and it was very touching to listen to the pipa playing on Xunyang River. But he is in a foreign land, and no one complains about the pain of lovesickness, so he can only express his feelings with music. The phrase "snow destroys people's temples" in the signature poem means that years make people old. Although there is no serious problem, there is no joy in it, and everything is fierce.
