During the Qingming paper-hanging season, Qiu Jinghui asks the bamboo partridge to help gather wild berries

"It is exactly the season to taste wild forest berries. They are perfect for making jam." News like this appeared in the newspaper. So Mother Mouse called Dr. Tree Frog, and the next day took the little mice outdoors for an outing, gathering all kinds of berries, making wild berry jam, wild berry jelly, wild berry cake, wild berry juice... and held a wild berry banquet, and all the animals in the forest came.

This is the picture book "Dr. Tree Frog's Wild Berry Snack Classroom," illustrated for children by the famous Japanese ecological painter Tatsuhide Matsuoka. I believe many adults have read this story to their children.
