Chinese law requires every Chinese person to undergo military training at the elementary, middle, high school, and college levels. Each phase of military training lasts at least one month.
Young Chinese are expected to have seen not only artillery shells, but even to have used mortars, to have had a rudimentary understanding of tank driving, Tank-Infantry Synergy, the use of landmines, and other weapons.
Of course, most of these students also don't know whether the caliber of China's large artillery is 152mm or 155mm.
