This series features Four Great Classical Novels of Chinese literature, turning the original stories into picture books for concentration games that are suitable for children to read and play. The picture books aim to help 3- to 8-year-old children gain a preliminary understanding of shapes, numbers, colors and historical stories in the process of listening to stories, counting animals, looking for things and observing characters, so as to cultivate children’s interest in the classics and traditional Chinese culture. This book is adapted from Outlaws of the Marsh written by Shi Nai’an (c. 1296–1372).
