Chrysanthemum was one of the most important flowers in ancient Chinese culture, known as one of the "Four Gentlemen of Flowers", and one of the common images in ancient Chinese poetry. Chrysanthemum poetry was an important form of literature in the Tang Dynasty. Many famous poets had written poems about chrysanthemums. For example, in the Tang Dynasty poet Du Fu's "Climbing High", there was a famous sentence,"Picking chrysanthemums and leisurely looking at Nanshan under the eastern fence", which expressed the poet's pleasant mood when picking chrysanthemums. In addition, the Tang Dynasty poet Bai Juyi's "Fu De Gu Yuan Cao Farewell" also used chrysanthemums as the theme to express the poet's love for nature. In the Song Dynasty, chrysanthemum poems were even more popular. Many famous poets had excellent works. For example, in the Song Dynasty poet Su Shi's "Ode to the Red Cliff", there was a line: "The halberd sank into the sand, and the iron was not destroyed. If the east wind doesn't go with Zhou Lang, the bronze sparrow will lock up the two Qiao in the deep spring."The famous sentence expressed the poet's longing for history. In addition, in the Song Dynasty poet Lu You's Spring Journey to Qiantang Lake, there was also a poem: " The wild path is black with clouds, and the boat is bright with fire. At night, I send a clear stream to the Three Gorge to miss you, but I don't see you coming down to Yuzhou."The famous poem expressed the poet's love for chrysanthemums during his journey. Chrysanthemum had an important position in ancient Chinese culture. It not only represented elegance and noble quality, but also was a poet's expression of history and nature.
