Themed around "childhood days that every grown-up has once gone through", this collection of photographs ranging from early efforts to recent works includes numerous pictures that were never before published in a photo book.

I don't believe that every person in the world yearns after his or her childhood. Every childhood has its times of grief and suffering. However, once our childhood days lie far behind us, and we find ourselves approaching the end of our life, I suppose we all remember our time as little kids with the same fondness that we're now looking at our own children with.
