This project aims to explore the state of urban life in a narrative picture book. It is a fiction story about how a middle-aged man Mr.M trapped in real life becomes brave enough to develop his ambition and take responsibilities after he goes through the world of shadow. I used model installation to make my characters and settings. Model installations are be made by mixed media: clay, cardboard paper, light, charcoal.The story is displayed with the placement and interaction between clay figures and figures on the flat paper, representing a relationship between flatness and reality. The man who is supposed to be a part of his life is detached in this way. To view the ebook: https://issuu.com/hezhuzhu/docs/mr_m_digital_book_final
