Practical and Practical

Okay, that's crazy enough. People carved pictures on stone walls thousands of years ago, but the people in the paintings are nowhere to be seen ten thousand years later. The stone wall disappears with the geological movement and will eventually cease to exist. The sorrow in the painting will eventually be traceless.

At night, memories come flooding back. The studious young man named "Xu Zihou" once traveled through time and space in the future and wrote two biographies for me with great enthusiasm, namely "The Learning of Heaven and Man: The Independent and Unafraid Wang Xitian and His Complete Book of Xitian" and "The Biography of Wang Xitian: He Cherished the Great Confucian Alone in the Divine Land, and No One Knows the Complete Book of Xitian". How long has he been dead? I don't remember either. What works does my complete list of Xitian books include? I don't remember either. I don't remember anything, it's like I suddenly lost my memory. I was probably overwhelmed with sadness. How can a sad person go through his own sadness? I think.
