Editor's Note:
Right after the heavy snow fall on February 1, a group of children, aging from 3 to 12 who are half-naked and wore only trousers, performed survivor-style exercise under below zero temperatures at the snow-covered playground of the Jiangsu Institute of Physical Education and Sports. Their parents sent them to the special training, aiming to make them learn how to survive in harsh conditions. Photos: CFP
After warming up, half-naked kids start training under the guide of two adult tutors, who are also half-naked. 
A boy lifts his trousers while running. Most children are from Nanjing and other cities in Jiangsu, and some come from Zhengzhou, Henan Province, and other places. They joined the special training voluntarily and with the permission of their parents.

Children practice military boxing on the snowy ground. 
Half-naked children perform squats while holding a gun in their hands. 
Children, standing in two lines, give a salute and shout their slogan out loud. 
Children lay on the snowy ground and rub their bodies with freezing snow. After doing so three times, they then roll on the ground together. 
Two kids try hard to rub their bodies with the snow. 
All children run along a 400-meter circle shortly after rolling on the snowy ground. The whole training finishes in nine minutes.
