Chrysanthemum has always been regarded as a symbol of loneliness, elegance and first frost, representing the gentleness and friendship of celebrities. Chrysanthemum is deeply loved by ancient China literati because it is not afraid of autumn cold, and many poems praise it. For example, Tao Yuanming, a great poet in the Eastern Jin Dynasty, wrote a famous sentence, "Pick chrysanthemums under the east fence and see Nanshan leisurely."
