Since the Immediate Action on Request reform in 2019，Beijing has taken the 12345 Citizen Service Hotline as the key to continuously promoting the consolidation and optimization of government service hotline resources，building the hotline into a “general customer service” of government services. So far，Beijing has basically completed the 32 hotlines listed by the General Office of the State Council in 2021，providing citizens with “one-stop” professional and standardized solutions for consultation，suggestions，requests，and other public services. By doing so，the 12345 Hotline becomes a vital channel that connects citizens and the government. Beijing not only brings together all other hotlines’ data into the 12345 Citizen Service Hotline，but also carries out data analysis to release its value for governance. These actions not only broaden the channels for reflecting social opinion and enhances the government’s ability to perceive public opinion and predict social risks，but also provide solid data support for governments at all levels to respond to people’s demands，resolve grassroots conflicts，and carry out scientific decision-making. With its reform of “Immediate Action on Request”，Beijing has become a model for precise governance of China’s mega-cities.
