During basic training, the young soldier Lei Feng did many good deeds in his camp and in the city of Yingkou without leaving his name (做好事不留名). He died on duty in 1962, at the age of 21. On March 5, 1963, Mao Zedong wrote the inscription “Learn from Comrade Lei Feng,” and March 5 became Learn from Lei Feng Day.
His diary, found and published after his death, contains the line “I want to be a screw forever” (我愿永远做一个螺丝钉).
