Spark was an underground publication that emerged in Gansu province in 1960, and was centered on the ongoing famine and the Great Leap Forward. Ultimately, 43 people, including the Rightist teachers and students who were connected with the publication, the peasants and the rural cadres who sympathized with them, were arrested and given long prison terms. Among them, three key figures were executed during the Cultural Revolution.
