This sentence came from the Tang Dynasty poet Wang Zhihuan's poem "Climbing the Stork Tower". The whole sentence was: "Drunken lying on the battlefield, don't laugh at the ancient war." It meant that even if you were drunk on the battlefield, don't laugh at me. How many people in history who went to war could return? This sentence expressed the cruelty and uncertainty of war. Even if people won the war, they could not recover the damage and losses caused by the war. At the same time, it also expressed the value of life and the yearning for peace.
