It is also a feeling that time flies. Li Bai's "Into the Wine" puts forward "Oh, let a man with spirit take risks where he likes, and never tilt his golden cup against the moon!" Eat, drink and be merry in time. And this poem, in addition to putting forward the idea of eating, drinking and having fun in time, repeatedly emphasizes the need to have a sense of urgency, perform one's duties, and even take into account things other than duties. This attitude of being happy but not lacking, the doctrine of the mean, is more comprehensive and profound in thought.
