What does it mean that the world is busy and the world is urgent?

Describe the busy and noisy scenes in the real world and the state in which people are in a hurry.

This poem comes from Du Mu, a poet in the Tang Dynasty, "The fence door feels cold in autumn." It describes a busy social scene and expresses the fast-paced and hasty reflection on real life. Remind people to stop at the right time in the busy life, appreciate the beauty of life and realize the true meaning of life.
