The autumn chrysanthemum has the qualities of both a martyr and a nobleman.
In the late fall, under the slanting sun, by the short hedge, a clump of yellow chrysanthemums opens proudly, defying frost and loneliness, and displaying valuable qualities no matter where they come from or where they go.
For more than 2,000 years, the spirit of Confucianism and Taoism has been influencing the Chinese scholars, and many of them harbor the idea that "being poor is to do good to oneself, and being rich is to help the whole world".
Despite the difficulties of the world, the literati also have a retired volunteer in their hearts, but the kind of optimism and joyfulness, cheerful and enterprising temperament, so that they have always refused to give up the lofty goals, and chrysanthemums are most sufficient to reflect this humanistic character.
