This Tang poem was written by Bai Juyi, a poet in the Tang Dynasty. It's an ancient poem written by Yuan Zhen, an old friend of Bai Juyi, who dreamed of his death nine years ago. There are 14 words of blood and tears, which are unparalleled in the history of literature.
The most striking thing about this ancient poem is that it is four words. It is hard to imagine that a poet can write such a poem, describing the distance between himself and his friends and their different situations.
Before we wrote mourning poems, most of them were just the feelings of sketchers, and few poems directly described the contrast between the two situations. After all, a person is in the underworld, and a person is still on earth. Poetry, including the psychology of China people, is very taboo against this contrast. Bai Juyi, on the other hand, can call the shots and directly expose their situation.
It's been nine years since Yuan Zhen died. Now I'm afraid everything in his grave has turned to sand, but he finally rests in peace. There is a very deep friendship between Yuan Zhen and Bai Juyi, but since his death, this friendship has never continued. Yuan Zhen was buried under the grave, and the soil eroded his body. Perhaps it has already turned to dust with the soil, but now Bai Juyi is gradually aging, and he just lives in the world temporarily with white hair.
Such a poem reminds us of the old man who died at home. Everyone will face death, and everyone will face the cruelty of describing Yuan Zhen to Bai Juyi. Each of us will die for a long time. Today, in the near future, we will be like Bai Juyi, "snow on earth", and I don't know when we will "bury mud under the spring and sell bones to the ground."
Perhaps this is the sorrow of life, but it is also the fate of life, and everyone can't escape it. However, the friendship between the two peoples can go through thousands of years, beyond time and space, and reverberate in our minds after thousands of years.
