The focus of the research has also expanded from individual experiences to collective experience. As part of the Project on Collecting the Historical Data of Chinese Scientists' Academic Life, and following the norms of historiography, I and other team members compiled oral interviews and accounts of Chinese scientists trained in the Soviet Union in the 1950s and 1960s. Through the procedures of data collection, candidate selection, framework construction and detailed presentation, I compiled the oral accounts of 16 Soviet-educated Chinese scientists, supplemented by photos, annotations and other information. These materials describe the lived circumstances and feelings of those scientists in the early days of the People's Republic of China and recreate the collective experience of this generation of scientists from multiple angles.展开更多
