 Chen is the youngest of five brothers of a peasant family from the village of Dongshigu, Yinan County, Shandong Province, approximately from the city of Jinan.When Chen was about six months old, he lost his sight due to a fever that destroyed his optical nerves.In an interview for the "New York Review of Books", Chen said that although his family did not identify with an organized religion, his upbringing was informed by a "traditional belief in virtue that’s present in Chinese culture—that might have some Buddhist content, but not necessarily that one believes in Buddhism."
