How is joy expressed in the title of the poem "Joyful Rain on a Spring Night"

The word "xi" in the title applies to the entire article. Although there is not a single word "happy" in the eight lines of the poem, the poet's joy is beyond words.

The first couplet writes about the arrival of spring rain: "Good rain knows the season, and when spring happens," the word "good" expresses the poet's praise for spring rain. Spring is the season when plants sprout and grow. When rain is needed, it begins to rain. The poet uses personification to praise Chunyu for his understanding of people, as if he understands people's wishes.

The couplet depicts the characteristics of spring rain: "Sneaking into the night with the wind, moisturizing things silently." It is accompanied by the warm spring breeze, taking advantage of the night to quietly spread over the earth, continuously and densely, moistening silently. All things do not seek to be known and have no intention of pleasing others. Chunyu has such a noble character, and the poet likes it very much.

The neck couplet describes the rainy scene on a spring night: "The night path is dark with clouds, and the river boats are only bright with fire." The poet hoped that the rain would be enough. He opened the door and looked out, only to see dark clouds in the sky and dark clouds on the ground. It was so dark that even the path could not be seen clearly. Only the fishing fire on the boat in the river showed a little light.

The last couplet "Looking at the red wet place at dawn, the flowers are heavy in Jinguancheng" is the poet's imagination: at dawn the next day after the spring rain, the entire Jinguancheng must be a scene of flowers and colorful flowers. A wet, heavy, red flower must be more lovable. If the flowers are like this, the crops in the fields will surely grow vigorously.

The spring rain brings vitality to the earth and brings people the hope of a good harvest. How can the poet not praise the spring rain!
