Fiber City—the collective name Fujian Textile and Chemical Fiber Factory—was founded in 1971. China's first production in the 1970s, one of the nine Vinylon factories located in Yongan City, Fujian Province, deep in the mountains, 3 kilometers outside the outskirts of the industrial town. Once glorious, it has been gradually lowering its curtains. The old factory buildings are mottled, its young workers are now gray-haired, and many have left. The documentary shows the fate of this big factory during the planned economy.
When the Cultural Revolution broke out, Yang Xiaokai was a senior high school student at No. 1 Middle School in Changsha. On January 12, 1968, he published an article entitled "Where is China Going?" which systematically put forward the ideas of the "ultra-leftist" Red Guards, criticized the privileged bureaucratic class in China, and advocated for the establishment of a Chinese People's Commune based on the principles of the Paris Commune. Yang Xiaokai recalled that his parents were beaten because they sympathized with Liu Shaoqi's and Peng Dehuai's views, and that he was discriminated against at school and could not join the Red Guards. As a result, he joined the rebel faction to oppose the theory of descent. Yang Xiaokai was later sentenced to 10 years' imprisonment for this article. Yang Xiaokai died in 2004. This article is a retrospective of his life.
