With the Supreme People's Procuratorate issuing the "Procuratorial Big Data Action Guide (2017-2020)," which points out the direction for procuratorial big data construction, it is required to fully apply big data and other related modern technological means to serve judicial case handling, procuratorial management, and the people, further standardize judicial behavior, solve problems such as judicial injustice, non-standard judicial practice, and insufficient effectiveness, improve the quality and efficiency of judicial case handling, enhance judicial credibility, and promote the development of procuratorial work in reform, strengthening in exploration, and advancement in innovation.
