From Tangshan's shoreline, you can see the strength of a city extending from land to sea. At Caofeidian Port, enclosed conveyors can move 9,000 tonnes of iron ore per hour.

What makes Tangshan's port special isn't just its size, but the fact that every load of iron ore embarks on a complete journey -- from port logistics to steel plants, and finally to high-end steel.

Here, the port and the industry aren't separate stories; they form one interconnected system powering northern China's future.
