The first of the post-90s generation in Beijing to undergo six months of Paramilitary Special Forces training has begun with 89 new recruits and 109 veterans.

The new recruits are all born after the 1990s. They are divided into three groups according to their physical qualities, and to receive different trainings, which will eventually weed out 40 percent of them.

The men will be pushed to their boundaries, especially during the so called “Devil Day” and “Devil Week” training, to challenge their physical and psychological limitations, fixing a solid foundation to become a member of the special forces.

Devil day training refers to a strengthened training day after every six normal days. And Devil Week refers to a grueling test of brains and brawn at end of the whole training period.

The young men have to hike overland for 10 kilometers wearing 20 kilograms of weaponry, and complete another 18 training tests within three hours without drinking or going to the toilet.
