China's barefoot doctor: ‘We did have shoes'

In 1968, Chairman Mao officially launched a scheme to improve healthcare in rural China, by giving thousands of people basic medical training and sending them out to work in villages.

They were known as the “barefoot doctors”.

Gordon Liu was one of them. Today he's a Professor of Economics at Peking University.
