During the worst years of the 1960 famine, a group of teachers and students at Lanzhou University decided to publish an underground publication, <i>Spark</i>, to alert Chinese people to the growing disaster and expose the authoritarianism of the Chinese Communist Party. Only two issues of this underground publication were printed before it was broken up as a counter-revolutionary group case and 43 people were arrested.
The author of this book, Tan Chanxue, was a key participant and helped save the memory of <i>Spark</i> from being lost. Tan was the girlfriend of Zhang Chunyuan, the magazine's founder, and participated in key moments of the magazine's short lifespan. She was sentenced to 14 years in prison, but was later released and rehabilitated, and taught at the Jiuquan Teachers' Training School. In 1982, she was transferred to the Dunhuang Research Institute as an associate researcher, and retired in 1998, settling in Shanghai.
It is largely through Tan's efforts that we know about <i>Spark</i>. She was able to look into her personnel file (<i>dang'an</i>), where she discovered the issues of the magazine, as well as confessions of the people arrested, and even her love letters to Zhang. She photographed this material and later it was turned into PDFs, which circulated around China starting in the late 1990s, helping to inspire books and movies.
