This poem comes from the Tang Dynasty poet Bai Juyi's Farewell to Ancient Grass. Among them, the poem "It rains like crisp in the sky" is "there is more silk rain over the capital avenue, and it is as smooth as butter". "Crispy" here refers to ghee, an edible oil made from milk or goat's milk, which is often used to describe something as delicate, smooth and soft.

This poem depicts the light rain on the streets of Beijing, showing the delicacy and wetness of the rain. At the same time, it uses "crisp" to describe the texture of the rain, further emphasizing the softness and wetness of the rain. This way of describing rain not only highlights the delicacy of rain, but also shows the nourishment of rain to the earth and life.

In addition, Rain Crisp not only depicts a natural phenomenon, but also shows the life scene of the ancient capital, making people feel a peaceful and harmonious life atmosphere. This delicate description also shows Bai Juyi's love for nature and life, as well as his keen observation and artistic expression.
