In early 1963, Lin Biao intensified the degree
of indoctrination in the army by starting a mass campaign within
the PLA to emphasize the basic values of service to the party.
The center of this campaign was the life of a young PLA soldier
named Lei Feng, who had recently given his life for his country.
... His life was presented as honest and sincere, but without
great drama except for his own family's suffering at the hands
of Japanese invaders, Guomindang rightists, and rapacious landlords.
... And he died, selflessly but unheroically, when a truck backed
over him as he was trying to help a comrade in trouble.
