Deng was a great calligrapher of epigraphy in Qing Dynasty, who was good at four books. Li Si and Li were the first students of his seal script, and later he studied Zen Monument, Sangong Mountain Monument, Tianbu Monument, Shi Guwen, Yi Qi Bi Fa, Hanshu and so on. He used official script as seal script, which broke through the barrier of imperial seal for thousands of years and opened up a new world for seal script in Qing Dynasty. His seal script is criss-crossed, and the font is micro-square, which is close to Wadang and Hanbei in Qin and Han Dynasties. The official script comes from the Han tablet, which is compact in structure, vigorous in appearance and magnificent in atmosphere, and also makes the official script of the Qing Dynasty look brand-new. Regular script takes the tablet of the Six Dynasties, and also takes the posture of Ou Yangxun and his son. The brushwork is firm and the words are tight, which makes it look vigorous and powerful. Cursive calligraphy mainly absorbs the cursive calligraphy of Jin and Tang dynasties, and its brushwork is soothing and elegant. Chinese cursive script, the weather is open and the artistic conception is boundless. Generally speaking, seal script has the greatest achievement, followed by Kai, Xing and Cao. Deng was also a seal engraver, who initiated the Deng School in Huizhou School. He entered the seal script with the small seal script and emphasized the brushwork. His style is vigorous, simple and graceful, and calligraphy and seal cutting complement each other. Deng's seal has the characteristics of "horse racing in a sparse place, but not in a secret place"
