Many of the workers are construction laborers or farmers. They wear knee-high rubber boots, down jackets, thick gloves and hats with flaps to protect their ears from the frigid air.

Every day since early December, tens of thousands of ice blocks have been prised out of the river and moved by truck to the venue of Harbin's annual winter festival, where they are used to build life-sized castles, pagodas, bridges and even a functioning hotpot restaurant.
