Since ancient times, it was a way to describe the scenes of war. It described the scenes of war very vividly and let the readers feel the cruelty and thrills of war. There were poems written in a similar way: - Don't you see that the Yellow River flows from heaven to the sea and never returns? - Can't you see the bright mirror in the high hall sad, white hair in the morning like black silk, turning into snow in the evening? - Life is full of joy, do not let the golden cup empty face the moon. - I'm born with talent, I'm sure it'll be useful. - Cook sheep, slaughter cattle, and enjoy the party. You must drink three hundred cups at a time.
