The month known as the Chrysanthemum Moon is the ninth month of the lunar calendar. In this month, the chrysanthemums are in full bloom and the garden is golden, bringing a splendid color to the earth. The ancients therefore called the ninth month of the lunar calendar the Chrysanthemum Moon, not only because the chrysanthemum is the representative flower of this month, but also because the chrysanthemum’s tough and proud character complements the late autumn atmosphere of September. In addition to the elegant name of Chrysanthemum Moon, September in the lunar calendar also has many other names, such as the Yiyi Month, Qingnu Month, Xiaotian Moon, Frost Moon, Late Autumn, Late Autumn, Canqiu, Suqiu, etc. These nicknames all describe the character of September from different perspectives. The Clothing Month means that this month is the time to prepare winter clothes. The Qingnv Month is related to the Qingnv in ancient mythology. It is said that she is in charge of frost and snow, and the frost season in September is the day when she comes to the world. Xiaotian month is because September is the harvest season of crops, and farmers start to be busy in the fields. Frost Moon directly depicts the scene of frost and dew condensing in September. Late autumn, late autumn and late autumn all express the meaning that autumn is coming to an end, while plain autumn gives people a fresh and refined feeling. In calligraphy works, these nicknames are often used as inscriptions, which not only add to the cultural connotation of the work, but also show the author's deep attachment and praise for autumn. Whenever people see these inscriptions, they seem to be able to feel the beautiful time when the garden is full of chrysanthemums and the autumn breeze brings coolness.
