Boxing in the hockey ring seems dangerous enough, but the Chinese take it one step further. Wearing nothing but a pair of shorts and sneakers, a group of winter swimmers entertained passers-by during a series of boxing matches performed on a block of floating ice. Held in Harbin City, the wacky competition had contestants punch each other with over sized boxing gloves while struggling to keep their balance on the slippery ice. One of the ice boxers lost his temper when the referee tried to stop him from hitting his downed opponent and knocked the “official” in the ice-cold water surrounding the ring.
