Inspired by the documentary Garden, Zoological (released in 2019, directed by Wang Mincheol), which tells the story of the animals at Cheongju Zoo, located at the foot of Uamsan Mountain in Cheongju, Chungcheongbuk-do Province, and the people who care for them, this pop-up book brings their stories to life. Garden, Zoological - Revised Edition vividly portrays the confined and lonely lives of wild animals behind bars, capturing their struggles in a powerful and immersive way.
