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." The meaning was," Those who lie drunk on the battlefield, don't laugh at me. How many people have survived the battlefield since ancient times?" This sentence expressed the cruelty and uncertainty of war. People on the battlefield often paid a huge price, and only a few people could return home alive. It also reflected the views of the people in the Tang Dynasty that war was an immoral act and that people should not participate in it.
