What are the artistic features of Wu Changshuo's seal script?

Seal script is Wu Changshuo's masterpiece. Yang Yisun studied his seal script in his early years. After the age of 30, he absorbed nutrition from the stone carvings in Qin and Han Dynasties and began to study Shi Guwen. From then on, he gradually deepened and never stopped. He established his personal appearance day after day until he was about 60 years old. After the age of 70, people are old, and their personal style is further matured and strengthened. Chang Shuo's seal script, on the basis of retaining Shi Guwen's fluent brushwork and simple style, breaks its fluent structure into a long and narrow structure, which is strewn at random from top to bottom. The pen is simple and thick, round and strong, square and folded. The pen is hidden, the pen is full, and the pen comes to an abrupt end or is gently lifted; In composition, there are no columns horizontally and no lines vertically, and the spacing between words is compact, dense and well-organized, so it is advisable to avoid it; In the method of using ink, the ink is full of charm, and occasionally the ink is exhausted and let nature take its course, which adds simplicity and simplicity more and more. Wu Changshuo's seal script is rooted in "Shi Guwen", which can not only change Tao Zhu, but also learn from other art categories. Therefore, no matter his official script, calligraphy, cursive script, painting and seal cutting, he can win with great weather. His masterpieces of seal script include Shi Guwen Axis, Yi Tian Alpine Union, Zhu Ren Shi Lian and so on.
