The French Impressionist School of Painting was a school of art in the late 19th and early 20th centuries, occupying an important position in the history of European art. The rise and development of the French Impressionist painting school originated from the social changes and people's new understanding of nature at that time.

Firstly, the emergence of the French Impressionist school of painting was a response to social changes at that time. In the late 19th and early 20th centuries, France experienced rapid development in industrial revolution and urbanization, resulting in significant changes in people's lifestyles and values. This change is also reflected in the field of art, where people begin to pay attention to the true feelings of nature and life, rather than traditional religious themes and mythological stories.

Secondly, the development of the French Impressionist school of painting is a response to people's new understanding of nature. Impressionist oil painting artists began to pay attention to the changes in light, shadow, and color in nature. They believed that the scenes in nature were variable and flowing, rather than static and unchanging. They transformed natural scenes into expressions of color and form through their own sensory experiences and observations, creating a new artistic style.

Finally, the brilliant chapter of the French Impressionist school of oil painting is attributed to its unique artistic style and innovative artistic techniques. The artists of the Impressionist school of oil painting reproductions focused on expressing the changes in light, shadow, and color in nature. They used a new custom oil painting technique - the stippling method, which dispersed colors on the screen, creating a soft and blurry effect. This technique makes the picture more realistic and vivid, while also increasing the visual enjoyment of the viewer.

In short, the reason why the French Impressionist school of painting can leave a brilliant chapter is because it reflects the social changes and people's new understanding of nature at that time, while also possessing a unique artistic style and innovative artistic techniques. Its emergence and development have had a profound impact on the history of European art, becoming one of the important sources of modern art.
