What is the premise for Deng to advocate calligraphy innovation?

During the reign of Emperor Kangxi and Emperor Qianlong in the Qing Dynasty, because Kangdi and Emperor Gandi liked the calligraphy of Zhao Mengfu and Dong Qichang, calligraphy prevailed for a while and filled the whole book world, thus forming a "cabinet-style" calligraphy style with the same character. At this time, more and more people of insight began to realize that only by breaking through this shackles can we embark on a new path of calligraphy art. Deng is a "head coach" who advocates reform and innovation. He promoted the rise of epigraphy and played an important role in the healthy development of China's calligraphy in Qing Dynasty.
