Du fu's quatrains
Poets can imagine the looseness of soil and the warmth of gravel without touching the spring sunshine, gentle breeze and flowers. The melting of mud and the warm experience of sand deepened the lightness and casual visual impression of Feiyan, and made the poet's whole body and mind immersed in the soft, harmonious and spring atmosphere. After reading this poem repeatedly, you will also feel that spring is not intoxicating and everyone is intoxicated. The success of this poem lies not only in the author's good observation of things, but also in the author's good observation of things.
