This series attempts to explore the constraints of time and knowledge on people from two perspectives. One is the selected knowledge makes people to follow seniors. Moreover, bustling people who tiredly choose to believe in the knowledge selected by power, and whether the independent thinking really belongs to every independent. And the wavering ones who don't have thoughts of their own in an online age where everyone can express themselves.

Each image in this series, in one form or another, continues to depict such a state of "society's desire, people's willingness". The halls, hallways and classrooms are all part of the series. When these rooms are taken apart, the element that appears most is the wall, by which people are surrounded in the picture, and by which they are surrounded in society. Society builds these walls of books so that people followed, and no one is “stupid” enough to break down the wall and find out what made that up.
