What are the characteristics of Huang Daozhou's calligraphy?

In calligraphy, Huang Daozhou has his own unique aesthetic point of view. He believes that calligraphy should be based on "charm". If it can be both "muddy" and "luxurious", it is a masterpiece of the upper class; The beauty of Wang Xizhi's calligraphy lies in his "exquisite brushwork and vigorous charm", so he can become the orthodoxy of calligraphy for thousands of years. However, the calligraphy below Tang Dynasty is "a little unsightly", or "colorful and biased in brushwork", or "a thousand strokes with one meaning". Therefore, Huang Daozhou vowed to adhere to the ancient laws of Wei and Jin Dynasties, and said in the Book of Quality: "The first part of the model law is eight points, and the nine middle parts of Cao Zhangji shall prevail. There are one or two things similar to Ji Jiu in "Little Grass Daughter Monument", which are only related to ancient and modern times, and the rest are far away from the same ear. The only authentic works are Zhong You's Shen Bao, Ji Zhi and Tomb Field, all of which are illegal, but their essence is enough to be removed. " While absorbing the essence of Wei-Jin calligraphy, Huang Daozhou also incorporated his own unique aesthetic principles into it, skillfully integrated elegance and simplicity, created interest and made it fluent, thus widening the distance with the people of the time and reaching the realm of "charm" and "muddy depth" that he had long longed for.
