China during the Cultural Revolution: women engineers discuss improvements to textile manufacturing machines. Colour lithograph after Luo Fengxian, 1975.

A scene in Yunnan Province Textile Mill ("Yun fang" for short). In the workshop there are rows of cotton-spinning machines. The workshop is divided into workgroups with charts at the end of each row indicating the daily production rates of the team. The painting shows some creative women workers who are assembling improved machines which they have designed themselves. All workers strive to be the first and to be paragons. To improve productivity and to economize on machine parts to the largest extent, workers try to use every possibility to innovate and to improve the configuration. The big box on the floor containing machine parts is marked "The Economical Box" ("Jie yue xiang"). Just as farm workers were impressed with the slogan "In agriculture, learn from Dazhai", so factory workers were impressed with another slogan, "In industry, learn from Daqing" (referring to an oil field in Heilongjiang Province that was renowned for the productivity of its workers)
