Meh, not schools, they don't have that many schools back then. More of that little "red book" thingmangy. But that's my point exactly, it was Mao's call to "culturally revolte," couple million people responded in their local communities and before soon it was a national movement of billions. Almost like a friggin zombie movie.
Remember, too, that most of the army Mao had desolved back into farmers during the great leap forward.
