Machines replace humans as labor costs keep rising

On one side of the roaring factory, machine arms cut, weld, press and gauge a steady flow of circuit breakers, while self-driving carts carrying piles of products shuttle between assembly lines and storage areas.

On the other side, dozens of young workers, side by side at their workstations, do the same job manually - assembling the electrical products that protect people's homes from short circuits.

These kinds of low-voltage electric products produced in Yueqing, a county-level city of Wenzhou, Zhejiang province, are installed in almost every city in the country and are shipped overseas for orders from across the globe.
