Zhang Shuqi (1900-1957), formerly known as Shizhong, Zishuqi, named Xiaozhuang and Qiluju in Nanjing. The room name is Komatsu Villa. People from Pujiang, Zhejiang. He used to be a professor at Nanjing Central University. During the Anti-Japanese War, he went to the United States to establish a painting academy, lectured on painting, and later settled in San Francisco. The main simple is to go to the complex, the style is unique. In the use of pen, Zhang Shuqi advocated "mainly simplifying and removing complex", and "simplicity" is simpler than image, rather than simpler than meaning. He believes: "The pen and the slip are the removal of the dispensable things, and the most essential part is retained. It is a high-level generalization, a stroke of paper, and both form and spirit." In the picture, the wild goose has a few strokes, with less and more. The brushwork is simple and complex, easy to use, and intriguing, which highlights the artistic conception and charm of the painting. 122*30cm
