The special task force of the Jilin Corps of Chinese People's Armed Police Force started their annual "devil training week" on Dec 10, aiming to sharpen their abilities in coping with emergencies under complicated circumstances.

The seven-day extreme training includes a 330-kilometer weight-bearing march and dozens of extreme training subjects in extreme cold (minus 30 degrees centigrade). It tests their physical strength, skills, endurance and psychology.
