Huai Lian Bai Yu is one of the commonly used rhetorical devices in Chinese poetry, which refers to the use of plant names for metaphor, symbol and other expressions. Sophora japonica, lotus, cypress and elm are all common tree species in ancient China, and these plants are often borrowed in ancient poetry to describe the temperament, character and situation of characters. For example, "The Sophora japonica flowers are all crowing, and Wen Daolong crosses the five streams." Sophora japonica and Zigui in this Song Dynasty poem express the author's homesickness and expectation for love. Because the flowering period of Sophora japonica is similar to the weeping season of Zigui, it is very tactful to use Sophora japonica and Zigui to compare homesickness and love in the poem.
Huai Lian Bai Yu is not only used in poetry, but also often appears in literary works and cultural inheritance. There are often symbols represented by flower trees in China traditional culture, and these objects are often used in folk stories, myths and legends, operas, novels and other literary forms. For example, in The Journey to the West, the great tree Qi Tianshu is Niu Mowang's close confidant and a leader among the wicked, and its name "Qi Tian" implies its imposing image. In A Dream of Red Mansions, Sophora japonica leaves and yellow flowers are a set of scenes in which Daiyu buries flowers. Yellow flowers symbolize the transience and impermanence of life, while Sophora japonica trees mean grief and grief.
The use of Sophora japonica and Ulmus pumila is not only to describe the beauty and vitality of plants, but also to embody and inherit a culture. It represents human's perception and understanding of nature and expresses the importance of harmonious coexistence between man and nature. In contemporary times, we can also express our inner feelings and thoughts, pay tribute to nature and inherit the spirit of culture through the rhetorical device of "Huai Lian Bai Yu".
