The youth off-campus practice base was transformed from abandoned schools, and various expansion projects such as high-altitude projects and venue projects were set up in the middle of the original runway. High-altitude projects include high-altitude broken bridge, grasping pole, facing difficulties, win-win, Luding bridge and high-altitude dependence. On-site projects include erection of power grid, island survival, blinding obstacles, hanging by a thread, maze and so on. These projects are conducive to cultivating the comprehensive quality of young people, and have a very good effect on improving the courage of primary and secondary school students and integrating into the team.
