This poem comes from Lu You, a poet in the Song Dynasty, "Going out of the fence to meet the cold in autumn night". The poet expressed his mental and physical exhaustion and exhausted mood in his poems. Among them, the word "exhausted body and mind" directly points out the tired state of the poet, while "when to die" reveals the poet's expectation for dawn, hoping that a new day will bring changes. "Tears wet blue" further deepened the poet's sadness, and "broken dreams" implied that the poet's hope had been shattered. Through vivid description and strong emotional expression, the whole poem makes readers deeply feel the fatigue and helplessness of the poet. This poem not only expresses the poet's personal feelings, but also reflects the difficulties and setbacks faced by ancient literati in the process of pursuing their ideals and ambitions. At the same time, it also encourages people to learn to persist and be brave and keep a positive attitude when facing difficulties and challenges in life.
