How to understand that because of those scattered past events, our childhood has the color of sunshine?

Therefore, we should understand that because of those scattered past events, our childhood has the color of sunshine: having the color of sunshine in childhood means that childhood is sunny, bright, beautiful and interesting, because the color of sunshine is golden, which is often used to express joy and beauty. Sporadic past events refer to some fragmentary things in the past, because those fragmentary past events have sunny colors in our childhood, which means that every time we recall those fragmentary things in the past, we feel that childhood is beautiful and interesting.
