Who can tell me something about the ancient line drawing in China? "Be more specific"

Line drawing is one of the technical forms of Chinese painting, which is mainly used to draw figures with double hooks or flowers and birds. Fine brushwork is always based on line drawing, which is related to the double hook couch of calligraphy. Li Gongxian of Wu Daozi in Tang and Song Dynasties developed it into an independent art form. This kind of painting reflects the different textures and changes of objects through the rigidity and softness of lines. For example, Gong Li's "Vimo Religion in the Song Dynasty" and "Fairy Battle Map in the Yuan Dynasty" spread to Wu Zongyuan, not only the characters are in full swing, but also the praise seats under Vimo are carved from the couch, all of which are carefully outlined with a pen. As a kind of Chinese painting, line drawing is also called line drawing. Today, the basis of learning figure painting should still lie in line drawing, which can start from copying and cooperate with sketch. Replicas such as Send the Moon to the Heavenly King by Wu Daoyue in Tang Dynasty, Yongle Palace Mural in Yuan Dynasty, and Chaotian Fairy War Map by Wu Zongyuan in Song Dynasty can all be used as models for copying. Modern excellent inner painting cartoons can also be used as a reference for line drawing learning. The line pattern of line drawing requires preciseness, not only accuracy, but also accuracy. Smooth and smooth, there is echo between pens. Lines and money are attached to each other, and the hair is coherent and pulled up and down. For example, Gong Li's "Five Horses" and Zhang Huai's "Nine Songs" have played an expressive role in the description of people and animals. Line drawing should not only learn from ancient masterpieces, but also learn from folk painters. They not only have a set of formulas for drawing lines, but also have great skills in drawing lines, whether they are firm lines, horizontal lines, round lines or various patterns. They can draw straight lines and round lines with different curvatures without rulers and compasses. Eighteen descriptions of characters are also called "eighteen descriptions of ancient and modern times" Yi Men Guang Bi and Wang Keyu's Coral Net in the Ming Dynasty describe that Wang Keyu's Coral Net is now Eighteen Descriptions of Ancient and Modern Times, or Eighteen Descriptions for short. The excerpts are as follows: You Simiao: such as Zhou Ju's iron line painting: such as Zhang Ma's locust painting: Ma Guxing's orchid leaf painting nails and mouse tail painting: Wu's mixed painting: multi-painting and pouting head painting: bald pen is also a summer clothes painting: Bu Xing's folding reed painting: such as Liang Kai's sharp pen and slender pen, olive palm painting: Jiangxi Yan Hui's jujube stone painting: sharp and big willow leaf painting: such as Wu Bian's Guanyin pen. The second main line drawing is orchid leaf painting. After the development of this line drawing, it is very powerful. Wang Ayu said, "A horse locust was painted by orchid leaves, or a willow leaf was painted by orchid leaves. I am afraid it is neither right nor wrong. " Orchid leaf description is a kind of description from tortuous and rich clothing lines to the back, which has its independence. It is characterized by uneven pressure and pen lifting from time to time, resulting in thick and thin lines resembling orchid leaves. The description of jujube stone and Liu Yemiao belong to this type. The representative painter of this line drawing method is Wu Daozi. Unfortunately, none of his works have been handed down, which can only be slightly confirmed by Born of Gautama Buddha and ancient books handed down for him. The line drawing in the picture is more dramatic than the iron line drawing. Should Dong be replaced? "Postscript of Guang Chuan's Painting" said: Wu Sheng painted figures like plastic, and when he looked around and covered them, he knew what they meant. His handwriting is as thin as a copper wire board, and the thickness of vermicelli is high or low, but the bones are high or low, which shows that the expressive force of his lines can reach a sculptural three-dimensional sense. He is good at orchid leaves, willow leaves and jujube stones. Mixed description of various methods. Many Buddhist murals he painted can be compared with Michelangelo who painted the Sistine Chapel in the Renaissance. And can be called a master of art who combines the achievements of China's line method. There are also many successors to this description, such as Li Tang's Picking Flowers from Wei in Song Dynasty, Yongle Palace Mural in Yuan Dynasty, and figure paintings by Chen Hongshou, Zhang Lu and Zhejiang painters in Ming Dynasty, all of which make good use of Ye Lan's line drawing. They may gallop between orchids and bamboos, so don't be innovative.
