Military training in Chengdu typically occurs during the beginning of the school year for students and during scheduled international or domestic exercises for personnel. For students ranging from middle school to university, mandatory military training usually takes place in late August or early September at the start of the academic year, lasting approximately one to two weeks. These sessions focus on physical exercises, marching drills, and patriotic education. For professional military forces, specific joint exercises have historically been held in the region at varying times. For example, the "Hand-in-Hand" joint counter-terrorism training between China and India has previously been conducted in December, such as in 2018 when it began on December 11. Other specialized events, like the "Mt. Everest Friendship" joint training with Nepalese forces, have concluded in late September. Additionally, aviation regiments in the area have been noted to conduct round-the-clock training exercises as early as May.
