The birth of a famous painting, tell me how this famous painting was born.

Wu Daozi [1](680-759), an 87-year-old immortal, was a painter of the Tang Dynasty in China. Please birth background: During the Kaiyuan period of the Tang Dynasty, General Pei Min died in his mother's home, and Wu Daozi was asked to paint ghosts and gods in the Palace of Heaven, so that his mother could be blessed. Wu Daozi made Pei Min's screen mourn, tangled in uniform, galloped with swords, became impassioned, frustrated and down-and-out, and thousands of people in the audience were all chilling. Wu Daozi undressed magnificently because he drew strong thoughts with his spirit and put pen to paper, which is a wonder of the world. Skillfully understand the cow, the wheel is flat, and everything is technical; And Zhang Xu's view of Gong Sundaniang's sword-dancing device is obsessed with cursive script, and Tao is to painting, which is probably the case! Besides, condescending to an expert is so heroic that ordinary people can't do it. Every stroke of a Taoist priest must be drunk, which is different from writing and is based on qi. In Chang 'an and Luoyang, Wu Daozi once produced more than 300 temple murals, including all kinds of supernatural figures, without the same trace. Wu Daozi used meticulous brushwork and dense brushwork in his early years. After middle age, his painting style became vigorous, with vigorous lines, full of movement, changing thickness and interweaving reality and reality. Moreover, the short interval between stippling and painting leads to his incomplete brushwork and unclear intention. Later generations combined his painting style with Zhang Sengyou's, making it a kind of "sparse" painting style, which is different from the "dense" painting style of Gu Kaizhi and Lu Tanwei. The Buddha's clothes painted by Wu Daozi are wrinkled and flying, which is called "the wind in the Five Dynasties" by later generations. His paintings like to use Jiao Mo to cross the lines and then understate the ink marks, which is also called "Wu Zhuang". Please share with me.
