"Stars" is a famous poem by Du Mu, a poet of the Tang Dynasty. Its main purpose is to express the poet's emotions and expressions about the passing years and the impermanence of life.
The poem begins with the sentence "The stars are as bright as frost and snow", comparing the stars to frost and snow, expressing the emotion of the rapid passage of time.
Then, the poet expressed his feelings about the journey of life through the sentence "Life is like a journey against the odds, and I am also a traveler." Life is short, and everyone is walking aimlessly. On the journey of life, It’s hard to find a true place to belong and stop.
Next, the poet uses the changes in the city as an example to describe the constant changes in the surrounding environment and reveal the truth about the impermanence of life. The last sentence, "Why use a whip for cattle, people are walking in empty classrooms" expresses the poet's insight into worldly fame and fortune and his attitude towards the complicated worldly affairs in concise language.
Taken together, Du Mu's "Stars" mainly expresses feelings about the short and fleeting life, expressing helplessness and indifference to fame and fortune. It is a poem full of philosophy and sorrow.
