What is the poem widely celebrated in the summer quatrains?

A man who is alive is a man; Die and become the soul in the soul.

Life is an outstanding person, and death is a ghost. "This is not a subtle combination of words, nor is it a clever touch-up of a few words; It is the essence of conciseness, the spirit of boldness and the fearless attitude towards life. That kind of awe-inspiring righteousness permeates between heaven and earth, making ghosts and gods change color in vain. " "Yes" is also "Yes". The poetess remembered Xiang Yu, the fierce overlord of Chu, followed the spirit and integrity of Xiang Yu and hated the current politics of those in power in the Song Dynasty. They all say take a step back and broaden the horizon. Not can't, don't want to, don't want to and don't go. A "no" pen, with its own charm, is better than an uncanny workmanship and is natural. A heroic spirit of "killing without humiliation" and "dying without fear without humiliation" spreads all over the paper and penetrates the back of the paper, which is amazing.
