It's really super simple for a candidate who takes a master's degree in traditional Chinese medicine. I have just been studying this piece recently. I'll try to analyze it briefly. Chrysanthemum: The flowers are big and strong, and the petals are long and dense, about 1~2 cm long. Smooth the corolla to the same thickness as the pedicle. The color is white. Chu Chrysanthemum: The shape is similar to that of chrysanthemum, but the flowers are smaller. Many shrivels are in the shape of velvet ball, and the flower heart is loose. Gongjuhua: The flowers are small, the petals are dense and short, and the color is white. The pedicel is green and bright, and the flower heart is golden yellow.
