I don’t know if everyone’s experience is similar, I only know my own growth experience. The bitter and sweet purity is like a string of multicolored glass balls, which are connected in a string by the lines called “innocence”, such as Buddha’s relic, which shines all over the world of ignorance. I still remember the boy who grew up in the village, so clean and sunny. I used to be simple, before I was 18. I used to love it, when I was 18. After so many years, I can still remember clearly all the things I have experienced, including the most subtle parts, or I can not detect what I have forgotten, but I am sure I remember the important parts.
