Lei Feng, a young Chinese soldier in the 1960s, is known for devoting his spare time and money to helping the needy. Lei died after being hit by a falling pole while helping a fellow soldier direct a truck on Aug. 15, 1962. A year later, Chairman Mao called on the nation to follow Lei's example, and March 5 of every year is designated "Lei Feng Day." [Xinhua]
