It’s an early December afternoon in Beijing. The first snow hasn’t completely melted and a freezing wind from Mongolia blows through the traditional hutong alleys. A handful of men on motorbikes arrive at Shichahai Lake, just a short walk from the Forbidden City.
Patches of ice float on the water. In about a month, when the ice will cover the entire surface, Beijingers and tourists will start ice skating. The men chat and laugh while removing their clothes until they’re wearing only bathing suits. Then they dive into the icy water. After another hour, the sidewalk is littered with clothes and towels like an outdoor swimming pool, and there are dozens of men swimming. Primarily retirees, some of whom are more than 90 years old, the winter swimmers have embraced this activity as a stress-relieving exercise.
