The appearance of Midian landscape is the product of the development of ink landscape to a certain stage. After the middle Tang Dynasty, due to the rapid development of calligraphy, Zen thought was deeply rooted in the hearts of the people, and the subjective requirements of artistic expression were accepted by more and more literati. The strict precepts of traditional landscape techniques bound artists' hands and feet. Mi Fei and Mi Youren boldly changed the tradition, weakened the use of lines, strengthened the movement of ink and wash, and opened up a new way to describe the misty and rainy scenery in the south of the Yangtze River. Teacher Wu in the Song Dynasty said: "The calligraphy and painting method is from the beginning to the end, and the book is easy to make, and the painting is simple and secret. However, simple and elegant, each has its own merits. " Yuan Wuhai also said: "The previous generation painted mountains and rivers to two meters, but the painting method changed greatly, and the meaning was too formal. Su Zizhan is so reasonable. " Fanfan's original works are hard to see, while Xiaomi has been handed down from generation to generation, such as Xiaoxiang's fantastic plan, Yunshan's ink opera, and Yunshan's virtue and meaning.
