A train runs through an apartment building. A maglev floats above its guideway. Driverless vehicles carry shipping containers between giant cranes. Across ten Chinese cities, extraordinary engineering is changing how people, goods and energy move.

In this video, we explore Chongqing, Shanghai, Hangzhou, Shenzhen, Guangzhou, Beijing, Suzhou, Tianjin, Wuhan and Chengdu. Discover the structures behind Liziba station, Shanghai’s magnetic levitation and layered streets, electric bus charging, automated ports, Daxing Airport’s layout, industrial coatings, water reuse and connected greenways.

We look at how these systems work, the practical problems they solve and the challenges that remain. Historical footage and design illustrations are identified where relevant.
