I saw this story when I was a child, but I was deeply impressed by an animated film called & gt, which was shot by Shanghai Animation Film Studio. I can't find the bound volume and selected volume of Childhood. Maybe a bigger library has it, but you can go to Tudou to read this cartoon, which may be better than the text version. Maybe your son will like it better. Please provide the address/program/view /uLn8ZGWrJsE/
