During the Cultural Revolution, Deng Xiaoping was sacked and sent to Jiangxi. Despite facing multiple high-pressure crises, he always remained firm, optimistic, and never changed his original aspiration. For his safety, the master of the factory arranged a special road for him. For three years and four months, Deng Xiaoping went to work along this trail every day. Later generations called it "Deng XIaoping trail".
