Huayang is what people are used to seeing. "Is it like a flower?" In Song Dynasty, Su Shi raised a question in his poems about Huayang handed down from generation to generation. It is precisely because of this sentence of Su Shi that Huayang, which was originally not intended to be watched by people, became a hot topic sung by poets of all ages. Yang, Salicaceae. Deciduous tree with wide leaves, dioecious and soft flowers. There are often scissors-like fragments on the edge of bracts, without perianth, cup-shaped disk and many stamens. Su Ci is anthropomorphic, writing like a beautiful woman longing for spring. It is superb and lifelike, and has become a swan song. Although there are endless followers, it is difficult to survive in the end. As early as the Northern Wei Dynasty, there was a poem about Yang Hua: "In February and March in Yangchun, willow blossoms. The spring breeze entered the boudoir overnight, and Huayang drifted to the southern home. When I left home, I felt very weak and found Huayang in tears. I will return to Shuang Yanzi in autumn and spring, and I will bring Huayang into the nest! " The metaphor of flowers for Huayang, a lover who fled to the south, is a pun, beautiful and moving, and it is a masterpiece of chanting flowers.
