How could the few people who had fought since ancient times understand this phrase?

This sentence came from a poem in the Liangzhou Ci by the Tang Dynasty poet Wang Zhihuan, which meant," Don't laugh at me when I'm drunk on the battlefield. In history, there have been countless people who fought in wars like me." This sentence expressed the hardships and cruelty of war and the emotions and thoughts that people might have when facing these experiences. It reminds us that war is a part of human society, but it also brings endless pain and sorrow. At the same time, this sentence also expressed a positive spirit, that is, although we lost everything in the war, we should not laugh at or belittle ourselves. We should cherish our lives and feel sad and sad for those who lost their lives in the war.
