In fact, I don't know how to define this book. You can say it is an interesting memoir, you can say it is a collection of sentimental romance novels, or you can even say it is not a novel at all. It's just that one day occasionally, I think of the people in my life who have gone far away or are still around me, and suddenly I feel, "Oh, some people have gone, some people have come, and there are always scenery around me that I can't get tired of." Just like I don't get tired of seeing horses galloping on the prairie, and I don't get tired of seeing boats floating on the grassland. I don't get tired of seeing the sunshine flowing on the pages of the book in the azure bay, and I don't get tired of seeing you walking on the road holding the book. There are always so many past, ongoing and upcoming scenery around you. This is the edge of time. Every moment we are wandering, suffering, but growing.
