As people rush to carry out altruist acts to honor one of China's most celebrated sons, a Shanghai cultural official has said such sentiments should last all year, not just for a month.

Tuesday marks the 50th anniversary of late Chairman Mao Zedong's call for people to learn from Lei Feng, a soldier who earned legendary status for his selfless behaviors.

March 5 was designated Learn from Lei Feng Day, and every year it motivates people to help those in need.
