The Three Character Classic, a traditional primer for children, holds up students who drove themselves. “One tied his hair to the beam. One jabbed his thigh with an awl. No one made them. They drove themselves to hard study.”
“One read by fireflies in a bag. One read by the light of snow. Their families were poor, but they never stopped learning.” The four students were Sun Jing, Su Qin, Che Yin and Sun Kang.
