The children's book "One Afternoon" is a unique, wordless work that stimulates imagination and fosters creativity in children. It tells two stories simultaneously: above, a boy fulfills his daily tasks and responsibilities, while below, his dog stays at home and embarks on its own adventures. This innovative narrative style allows young readers to interpret the story themselves and develop their own tales. The engaging illustrations by Hsin Yu Sun support the visual storytelling and invite exploration of the details in the images. The book is ideal for children aged 5 and up and is excellent for promoting reading comprehension and imagination.
