Meticulous painting became popular in the Tang Dynasty. Therefore, the reason why outstanding artistic achievements can be achieved lies in the maturity of painting techniques on the one hand and the improvement of painting materials on the other. Gongbi painting must be painted on silk or rice paper treated with alum. In the early Tang Dynasty, the improvement of silk materials promoted the development of meticulous painting to a certain extent. According to Mi Fei's History of Painting, silk was born in ancient paintings from the early Tang Dynasty to Wusheng, Zhou and Han Wo. Later, it was cooked in hot soup and powdered like a silver board. It pretended to be a character and was well written. Generally speaking, meticulous painting needs to draw a manuscript first, and a complete manuscript needs to be revised repeatedly before it can be finalized. Then cover it with rice paper or plastic alum silk, first outline it with a small pen, then color it with the class and render it layer by layer to achieve the artistic effect of both form and spirit. For example, autumn photos of Chen Zhifo.
