What is the first couplet and peaceful couplet in Du Fu's Moonlit Night?

Moonlit Night is a five-character poem written by Du Fu, a great poet in the Tang Dynasty. It is the author's work of longing for the moon and homesickness when Chang 'an was banned. With the help of imagination, this poem expresses his wife's thoughts about himself and his own thoughts about his wife. The first association is like a wife looking at the moon in Zhangzhou, missing herself, and telling the poet's homesickness in Chang 'an. Zhuan Xu said that children look at the moon with their mothers, and they don't understand their mother's feelings of missing their loved ones, which shows the poet's suspense about children and care for his wife. "The Neck Belt" is about an imaginary wife who looks forward to the moon and is full of sadness. The tail couplet pinned the hope of welcoming the bright moon together in the future, reflecting the suffering of lovesickness today. The whole poem is novel in conception, well organized, clear in words, sincere and touching.
