Deng (1743- 1805) was born in Huaining, Anhui. Seal engraver and calligrapher in Qing Dynasty, founder of seal engraving of Deng School. At the beginning, Yan's name was stone statue, which avoided the taboo of Emperor Jiaqing, so he used the line character, and later he became more stubborn. Because he lives at the foot of Wangong Mountain, he is also known as Taoist priest, Wanbai Mountain, Feng Shui fisherman and Longshan firewood, and he is not very good at seal cutting. He lived in Jinling Mei's house for eight years, copying rare stone books collected since Qin and Han Dynasties. He became a master of four-body calligraphy, especially in seal script, with Qin Lisi and Tang Liyangbing as disciples and a little Li Yi as disciples, which is called a masterpiece. Honest and clean, travel around famous mountains and rivers, and be self-sufficient in books. There is "Wanbaishan people seal cutting occasionally". When Deng was a child, his family was poor and his social status was low all his life. He himself said: "I tried reading at the end of my childhood and tried everything." When I was thirteen or fourteen years old, my heart was whispering and I took pleasure in books. At the age of twenty, my grandfather brought it to Shouzhou, and I can teach myself and live to this day. People don't treat each other like literati. " Such a "coarse cloth" with little reading has grown into a great artist by unshakable faith, tenacious will and hard exercise. After seventeen, he began to carve his own food with books. After the age of 30, through the introduction of friends, I gradually got to know friends such as the three Mei brothers in Nanjing, and visited the rare epigraphy books collected by the Mei family. Every famous inscription always has to be copied more than a hundred times, so I got up early and got greedy for black, which laid a solid calligraphy foundation for seal cutting in the future. So at that time, people evaluated his four-body calligraphy as the first person in Qing Dynasty.

Deng's seal script style is based on the Taishan stone carvings in Qin Dynasty, and the temple stone que and stone que Ming in Han Dynasty also played a great role in his book. This is from the shape and posture of his seal script. The brushwork of his seal script, that is, the form of opening and closing, is mainly taken from Huashan tablet, Zheng Gu tablet and a large number of small seal scripts on tile in Qin and Han dynasties.
