There is a saying of "Ruyan Liu" in the poem. Why does Liu smoke?

Ruyan Liu means that in early spring, willows grow buds, yellow and green. From a distance, it is hazy, like smoke and fog, so it is a willow. The weeping willows born by the water often grow in pieces, lush and dense, and the buds begin to grow, which looks like a cloud from a distance. Coupled with the breeze, the willow branches are smart and light as smoke. This is a combination of scenery. Ruyan Liu mostly refers to the beautiful scenery in the south of the Yangtze River. There is much water in the south of the Yangtze River, the temperature rises in spring and the water vapor evaporates, which will also increase this visual effect. The ancients often used "like smoke willow" to describe the density and green of willow.

Gao Ding, a poet in the Qing Dynasty, wrote "Village Residence": "In February, the grass grows long and the willows on the embankment are drunk with spring smoke." Describe the spring scenery in the countryside. In February of the lunar calendar, grass gradually germinates and grows around the village, and orioles fly around. Willow covered with long green branches, swaying in the wind, as if gently stroking the bank. The evaporated water vapor between Shui Ze and the vegetation condenses into smoke, and the willow seems to be intoxicated by this beautiful scenery.

In the sentence "Liu on the embankment is drunk with spring smoke", Liu is written as a person, Liu is intoxicated with the misty scenery, and people are intoxicated with the smoke and willow map. There are paintings in poems and poems in paintings, and a strong sense of spring is fully revealed in these two poems. In ancient poetry, the image of willow is often associated with love. For example, Liu Yuxi's "Nine Poems of Yang Liuzhi" in the Tang Dynasty: "The willow blossoms are bright, and Jiang Shuiping sings on the Langjiang River."

The poem depicts a fresh and beautiful picture with the image of willow: green Ruyan Liu, floating in the wind, spring water like a mirror, reflecting the new green of the whole river, and the quiet and beautiful girl by the river is full of beautiful and sweet dreams.

A burst of singing accompanied by a faint spring breeze aroused the girl's feelings, and her eyes were full of emotion. The girl looked up, and a boat carrying a man and a distant song slowly crossed the mirror-like water, causing ripples in her heart. The graceful willows show the girl's love for spring.
