How do they do it? -

Chinese workers use a machine to cut out large blocks of ice from the frozen Songhua River.

For weeks before the festival, workers collect and transport nearly 200,000 cubic meters (7.06 million cubic feet) of ice to the site.

How do they do it? - Most of the cutters are reportedly farmers from nearby villages who start work before the sun rises, at bitterly low temperatures, and earn about US$35 per day.
