Recently, the State Council issued the "Five-Year Action Plan for Deepening the Implementation of the People-Oriented New-Type Urbanization Strategy", which mentions accelerating the construction of affordable housing, dual-use public infrastructure, and the transformation of urban villages. Increase the construction and supply of affordable housing, speed up the solution to the housing difficulties of salaried employees, and stabilize the expectations of salaried employee housing. Through various methods such as demolition and new construction, renovation and upgrading, and demolishing and renovating, promote the transformation of urban villages, effectively eliminate safety risks, improve living conditions and ecological environment. Promote the construction of dual-use public infrastructure for flat emergency response. In the mountainous counties (districts) within the jurisdiction of super-large and mega cities, build a batch of tourist residential facilities with isolation function, upgrade a batch of medical emergency service points, build or expand a batch of suburban warehouses, and improve the city's ability to respond to emergencies.
