CGTN How can a city hear its people before they even speak? In Beijing, the answer starts with a phone number: 12345. Over the past seven years, this hotline has handled 180 million requests from residents and businesses, with resolution and satisfaction rates both above 97%. But the real story is not just the calls that come in. It is what technology does with the information. Every day, AI-powered systems sift through the data, grouping complaints by keyword, location and urgency and generating heat maps that show where the city is struggling. Analysts use these patterns to anticipate emerging problems: which neighborhoods repeatedly experience issues, which disputes peak in certain months and which types of complaints arrive in waves. A single case tells you little; the data can reveal much more. For example, if elevator complaints in one district keep climbing, maintenance or renewal needs may be mounting. The data does not just record the past. It points to the future. This is where "One Topic a Month" begins. Every month, algorithms identify a high-frequency problem in the data and bring it to the attention of a municipal department. Three levels of government work together. The goal is not to resolve a single case, but to address an entire category of problems. Yet technology alone cannot govern a city. Volunteer "lane managers" walk the alleys, spotting problems before they grow. Residents, businesses and community workers all become part of the early-warning system, providing eyes and ears that no algorithm can replace. The result is a city that no longer waits for the phone to ring.
