China during the Cultural Revolution: a young woman doctor in a fishing village preparing acupuncture needles. Colour lithograph after Peng Yuzhang, 1975.

A young woman doctor who works for a village's Cooperative Medical Station is sitting in front of fishing equipment; she is taking some cotton from a first aid box to clean an acupuncture needle. This is a typical fishing village on the South China Sea, and the woman doctor is one of the 'farmer doctors', so-called "Barefoot doctors" (chi jiao yi sheng) in the 1970s. These doctors were also local fishing or farming people and sometimes also members of 'educated youth' ('zhi shi qing nian') from urban areas. Their motto was "Use a silver needle to cure hundreds of illnesses; use a red heart to warm thousands of families"
