PS:

In the first year of Yuanhe (806), Bai Juyi was appointed as county commandant (now Xi zhouzhi county). One day, my friends Chen Hong and Wang Zhifu and I visited Xianyou Temple near Ant, and talked about Li Longji and Yang Guifei. Wang Zhifu believes that something as outstanding as this will disappear with the passage of time if it is not polished. He encouraged Bai Juyi: "Lotte is deeper than poetry and deeper than love. How about trying to make a song? " So Bai Juyi wrote this long poem. Because the last two sentences of the long poem are "the earth lasts forever, and the sky lasts forever;" One day, both will end, and this endless sadness will last forever. "They called this poem" The Song of Eternal Sorrow ". At the same time, Chen Hong wrote a legendary novel "Song of Eternal Sorrow".
