The origin of its name is named after the wonderful poem "Zhi in the garden and Li in the orchid" left by the patriotic poet Qu Yuan when he traveled here.
Later generations (Qing Dynasty) Zhang Zhidong's ingenious idea of "Talking about Yellow Crane in Boxing Vertebra, Green Snail in Plate and Lilac in Flower" embodies extremely touching poetry and painting. Lan Zhi is evergreen and full of vitality, with small yellow flowers in the middle of the petiole. The fragrance permeates all around, neither as strong as the fragrance of roses, nor as sweet and greasy as the fragrance of osmanthus, nor as light as the fragrance of plum blossoms.
