Wu Changshuo (1844- 1927), formerly known as Jun, also known as Cang Shi, also known as Kutie and Dalong. A famous painter, calligrapher and seal engraver in the late Qing Dynasty, a representative of "Houhai School" and the first president of Hangzhou Xiling Printing Society. Wu Changshuo, Xu Gu, Pu Hua and Ren Bonian are also called "the four outstanding Shanghai figures in the late Qing Dynasty". As far as his paintings are concerned, he is best at freehand brushwork flowers, which is greatly influenced by Xu Wei and Badashan people, and also by Zhao and Ren Bonian. In particular, the application of epigraphy calligraphy in painting, such as bending iron, has formed a unique painting style rich in epigraphy. He himself said, "The strength of my life lies in my ability to paint by writing." He often writes Mei Lan with a brush and grapes with weeds. The flowers and trees and flower stones we made are bold in brushwork, transparent in paper back, unrestrained in vertical and horizontal directions, magnificent in layout, almost sketchy in composition, preferring to adopt the pattern of "zhi" and "female", or oblique, combining reality with reality, with prominent themes. His paintings are dripping with ink and rich in colors. Like Zhao, he likes to use rich contrast colors, especially western red, which is strong, bright and full of charm, shaking the flagging trend of the late Qing Dynasty, opening up a new situation of modern freehand brushwork and forming a "great freehand brushwork" expression method that affects the modern Chinese painting world.
