Ministry of Housing and Urban-Rural Development: This year, another 50,000 old communities will be renovated to build a number of complete communities. The purpose of urban renewal is to make cities more livable, more resilient, and smarter, so that people can live more comfortably, securely, and happily in the city.

Last year, 66,000 urban renewal projects of various types were implemented across the country, with an investment of 2.6 trillion yuan completed. The underground pipe network is not only the "lime" project of urban construction, but also the "conscience" project.
