Chinese people swimming in winter - will you take this challenge?

Winter swimming is done typically in outdoor locations (open water swimming) or in unheated pools or lidos. In colder countries it may be synonymous with ice swimming, when the water is frozen over. This requires either breaking the ice or entering where a spring prevents the formation of ice. It may also be simulated by a pool of water at 0 °C, the temperature at which water freezes.
