What's so special about Xu Xi School of Painting? What is the impact on future generations?

Painting school is what we call "Xu School". As one of the famous flower-and-bird painting schools in the Five Dynasties, Xu Painting School still has great influence on later generations. As a representative figure of Xu School, the Southern Song Dynasty also left a profound influence on later generations. His paintings are very natural and simple, revealing true feelings, letting others immerse themselves in them and enjoying the birds and flowers. Xu's pen and ink skills still have a great influence on later generations. When Xu Xi's grandson, Xu Chongsi, was born, the reputation of Xu Xi School of Painting became more and more famous. Later, it was developed by Zhang Zhong, Wang Ruoshui, Shen Zhou, Chen Daofu, Wen Zhiming, Xu Wei and others in the Ming Dynasty, and finally gradually became a set of freehand brushwork flower-and-bird paintings. Later, it competed with the yellow flower-and-bird painting school, affecting the flower-and-bird painting circle in Song, Yuan, Ming and Qing dynasties for more than 1000 years. The world commented like this:

The flowers and birds made by Xu Xi are light in shape, simple and natural, fresh and elegant, and have a unique "drop ink method". "No bone stains, indifferent to the wild, can write a treasure, fresh and free and easy style. [1] Pay attention to the outline of ink bone, lightly apply color, and reveal a chic style, so later people call it' Xu Xiye Yi'. Xu Xi is good at painting flowers and bamboo, birds and fish, fruits and vegetables, and grass insects. When he has nothing to do, he will walk in the garden. Most of the scenery he saw was wild bamboo, waterfowl and deep-sea fish, garden vegetables and medicinal seedlings in Hua Ting. Every time he meets these scenes, he will observe them carefully, so everything he writes is full of vivid interest. At the same time, in painting, he changed the light color that has been popular since the Tang Dynasty, and created another expression method of ink drops, that is, the branches and leaves of flowers were written in ink first, and then colored. This theme and painting method can express his feelings and aesthetic taste as a Jiangnan Chu Shi. Xu Xi and Huang Quan both represent the latest level of flower-and-bird painting in the Five Dynasties, and both have important historical positions. Xu initiated ink pastel painting and freehand brushwork flower-and-bird painting, which formed one of the two major schools of flower-and-bird painting, and had a far-reaching impact on later flower-and-bird painting.
