Tiantongyuan, a sprawling Beijing neighborhood, is recognized as Asia's largest residential community. It's also a major draw for the "new Beijingers" who are settling in the city. However, the density and complexity of its population exacerbates the challenges faced by the local authorities, in managing it. In the CGTN documentary "Hotline Beijing,"we meet the grassroots officials who are working tirelessly to address the concerns of the local community, from long-term residents to new arrivals and those just stopping briefly, and we hear about the crucial role played by the Beijing 12345 Citizen Hotline in making China's capital feel like home for everyone.
