About a week ago, at around midnight, I was jolted awake by a loud noise. Living next to railway tracks, I am no stranger to the occasional rumble. But this one was loud enough to wake me even with earplugs in. So I called the only number I knew could help: the hotline for swift response to public complaints, 12345.
The operator politely confirmed my location and told me that someone would get back to me within a few minutes. Five minutes later, I received a call. I was told that urgent maintenance work was being carried out on the railway tracks and was given an estimate of how much longer it would continue. And, almost like clockwork, the noise stopped when the stated time was up. I went back to sleep, but the experience stayed with me. Not simply because my immediate problem had been addressed, but because of the system behind that seemingly ordinary phone call.
So I decided to take a deeper look at how a city of more than 20 million people turns individual complaints, questions and requests into concrete government action. And what does a hotline reveal about the way a city approaches governance?
From the mayor's hotline to a citywide governance platform
China's government hotlines have a history stretching back several decades. Some cities began introducing services known as "Mayor's Hotlines" in the 1980s, giving residents a direct channel to raise concerns with local authorities. Over time, cities developed and consolidated their public-service hotlines, with 12345 becoming the unified number for non-emergency government services.
In Beijing, the hotline has evolved into something much larger than a telephone service. The city's "Swift Response to Public Complaints" mechanism, launched in 2019, places 12345 at the center of a broader governance system designed around rapid response, efficient handling, timely feedback and, increasingly, proactive problem-solving.
The scale of Beijing's 12345 system is striking.
Over the seven years since the launch of the reform in 2019, the platform has handled approximately 200 million requests, including inquiries, complaints, requests for assistance and suggestions.
According to the municipal government's 2025 Annual Data Analysis Report, the hotline handled 25.802 million requests from residents and businesses in 2025, a 6.6% increase from the previous year. That amounts to approximately 70,700 requests a day.
This is where the principle often summarized as "the street whistles, the department responds" becomes more than a slogan. It reflects an effort to connect residents' concerns with the government departments responsible for addressing them, without requiring residents to navigate the administrative structure themselves.
Sharing experiences, exploring solutions
As cities expand and urban life becomes increasingly complex, the relationship between residents and local governments also changes. Issues such as housing, transport, employment, consumer protection and access to public services often require coordination across multiple departments and levels of administration.
A single point of contact offers residents a way to navigate that complexity. But can the experience of a city such as Beijing offer useful insights for other urban centers facing similar challenges?
