Between the snowstorm and the earthquake in 2008, the 16-year-old protagonist returned to his strange hometown and once again became a left-behind boy, a transfer student, and a "bad student" in an ordinary class. He is silent, precocious, uses reading to understand the present, and uses words to record life. Being fed by books, confirmed by criticism, and said goodbye again and again. With slow and restrained writing, the novel traces how an "out of time" teenager chooses to live on a longer scale in the popular era - not pursuing being understood by his peers, but pursuing being verified by time. "Light" is not a story about epiphany, but the process of how a person is slowly shaped by a few books, a few words, and a few people.
