Yen Jinchao, one of the farmers who signed the secret document in 1978.
In 1978, a group of farmers in a Chinese village called Xiaogang wrote a secret contract and hid it in the roof of a mud hut.
They were afraid the document might get them executed. Instead, it wound up completely transforming the Chinese economy.
On today's show, we travel to Xiaogang, and hear the farmers' story.
