Through extensive grassroots fieldwork, Josef Gregory Mahoney, professor of Politics and International Relations at East China Normal University, has personally witnessed China's whole-process people's democracy. According to Mahoney, this democracy is not only reflected in the high-level platform of the "Two Sessions," which orchestrates national development, but is also deeply rooted in vivid grassroots practices. From witnessing hundreds of millions lifted out of absolute poverty in rural and urban areas, to investigating how the "12345" civic hotline utilizes AI and big data to modernize governance, he has experienced the seamless synergy of China's top-down and bottom-up democratic mechanisms.
