Drunken Lord Grim on the battlefield, since ancient times how many people have fought? What did he mean?

This sentence comes from a poem in the "Liangzhou Ci" of the Tang Dynasty poet Wang Zhihuan,"Drunken on the battlefield, you don't laugh at the ancient war, how many people have returned?" 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 safely? This sentence expressed the poet's feelings for history and worry about the future. In ancient times, wars often happened. Many warriors fought bravely for the interests of the country and the people, but the result was often tragic. Many warriors lost their lives and even left irreparable regret. Therefore, this sentence expressed the poet's disgust for war and his desire for peace.
