The rivers and mountains are beautiful in Chiri, and the spring breeze is fragrant with flowers and grass.
Swallows fly when the mud melts, and mandarin ducks sleep in the warm sand.
Du Fu's "Quatrains"
The bright sunshine, the gentle breeze, the singing of birds and the fragrance of flowers are deeply felt by Du Fu. The poet can imagine the looseness of the soil and the warmth of the gravel without touching them; The experience of the melting of mud and the warmth of sand deepens the visual impression of the lightness of flying swallows and the coquettishness of mandarin ducks, so that the poet's whole body and mind are immersed in the softness, harmony and spring. If you read this poem repeatedly, you will also have the feeling that everyone will be intoxicated even if spring is not intoxicating. The success of this poem lies not only in the author's ability to observe objects, but also in the author's ability to understand physical conditions.
