The digitization of ancient characters allows ancient writing materials to break the limitations of time and space. The application of digital technology can also help the interpretation of ancient writings and contribute to the protection of original materials. After more than 20 years of efforts, the research on digital processing of Chinese ancient characters has made a series of attempts in ancient character database and query system, big data platform, ancient character input software and recognition software, and achieved a series of achievements. In the future, we need to make continuous efforts in the interdisciplinary talent training of Chinese Palaeography and computer science, the cooperation between different research institutions, and the openness of digital achievements.
