Shen Wei, a tramp, became popular because he often squatted under subways and street lamps, reading books such as Shangshu and Analects of Confucius, and was photographed by passers-by. In the eyes of most people, tramps are the lowest class in society, without knowledge and culture, and they are people who live in vain! Shen Wei, a tramp, used to be a college student and civil servant in a university in Shanghai, so it is rare to see such a cultured tramp. The strong sense of contrast makes Shen Wei a network celebrity today.
