Deng's seal script is vigorous, rich in flesh and blood, and mellow; Structurally, Qin Zhuan's folk prescription was changed to long and narrow, and the top and bottom were changed to tight and loose, sparse and impermeable; In the use of pens, Li Fa is used as the seal, and the transportation is straight and paved, turning around the front, and the front is broken with strength. It has a very obvious pressure increase change, which has changed the tradition of cutting the seal for flattening for hundreds of years. Because of this, later generations spoke highly of it, and Kang Youwei called it "the masterpiece of seal cutting", "Deng was the master of seal cutting and Mencius was the master of Confucianism". Later generations of seal engravers all respected Deng Weikai's model. Deng was very confident in his official script, claiming: "My seal is inferior and my beauty is undiminished." As an official, Deng likes to use seal script and Wei Bei's brushwork, which has broken the long-standing stereotype of traditional official script in terms of typography, brushwork and composition. Its official script is square, beautiful and pure; At the turning point of strokes, there are many kinds of seal meanings, which are round and smooth; In terms of composition and layout, it is vertical, horizontal, open, easy, heroic and free and easy. Deng's official script can stand out from the world's description of the shape of the Han tablet, and explore the spirit through the concealment and weathering of the knife carving and ink extension, which has unique significance in later generations.
In addition, Deng is also good at regular script and cursive script. His regular script is due to the inscriptions and stone carvings of the Northern Dynasties. His stippling is full and rich, with neat and steady structure, firm brushwork and multi-purpose pen collection, which has the trend of vigorous development. His cursive brushwork is often based on the brushwork of Zhuanli and Weibei, and his brushwork is magnificent and changeable. Its disadvantage is that it is slightly weak and beautiful, so Bao said, "Leave a mat for the latecomers to choose their place."
There are many works handed down from generation to generation by Deng, including Caotang Collection, Wen Xin Diao, Comment on Li Shuping by Song Ao, Cross-dressing by Zhou Ming, Hai Wei Long Shi Lian, Thirty-seven Sons of the Sea and so on.
