"Chrysanthemums, like people with lofty ideals, are old-fashioned and fragrant." (Song Luyou's "Late Chrysanthemum") On the first part, Qiu Ju made a clear intention, warning himself to be indifferent to fame and fortune and live quietly. It's autumn, the vegetation is withered, the mountains are cold and the water is thin, but the chrysanthemum "does not grow with the grass, but it can make a hundred flowers flourish." (Ming Li Mengyang's "Chrysanthemum") Ao Shuang is in the breeze, and it is full of beautiful faces and fragrance.

As Lu You, a poet in the Southern Song Dynasty, sang: "Chrysanthemums are like people, and they are independent. ..... have been scattered, see these yellow branches, high sentiment and quiet chastity, and the big section is tight and just "("Tao Yuanming's cloud three paths are still covered with chrysanthemums, and I feel this poem because of reading it ").

as one of the core elements of Chinese fine traditional culture, honesty is the excellent quality of "clean wind with two sleeves flying into the sky, without an inch of cotton in the south of the Yangtze River", the lofty spirit of "don't be praised for its good color, just keep the clean air full of dry Kun", and the social ideal of "the road is also good, and the world is public".
