In this book, Zhu Erduo will introduce us to a new classmate - Blue-Eyed Tom! He is an all-round classmate who can repair water pipes, get "tree climbing lessons" included in the curriculum, and make "chopstick dance" become the recess exercise. He is not only good at repairing things but also at mending the broken hearts of his good friends. What's more, he teaches us to bravely express ourselves and say "no" to unfair things. Facing the all-round repair friend who is about to leave, how will the grown-up Zhu Erduo face this parting?
