during the 1966-1968 the Cultural Revolution was out of control
the Red Guard were running amok in China, original concept was to purge the "bourgeoisie force" in party and administration.
now there burring Buddhist & Taoist temple and schools and university.
murdering priest, politician, bureaucrats, teacher and common people.
there was one case were group of Red Guard massacred another, about skirmish on the layout of Mao little red book.
it had a eerie parables what happen later in Cambodia under Khmer Rouge
in 1969 Lin Biao had to give the order to Army to break down the Red Guards in China
this phase is very interesting because it potential for many POD
like what if Lin Biao murder Mao or the PLA get divided between Lin Biao and Mao ?
or what if fanatic Red Guard group attack Soviet border patrol ?
