Lin Liuyin, a writer of experimental literature, seeks the limits of self-expression in a city where reality and fiction intersect. Together with "Masked" Zhou, artist Chen Wanhua, logician Su Shiji, and bar owner Wang Yichang, he experienced a series of absurd and real life experiments: from the writing challenge of split personality, to the fragmented observation of urban daily life, to the philosophical competition in the late-night bar. The three volumes respectively revolve around the reconstruction of identity, cognitive dissociation, and the boundaries between people. The ups and downs of humorous dialogue, concise and compact plot advancement, explore the collision between people and themselves, others, and society, and finally reach a strange destination on the boundary between fiction and reality.
