Preface
For a long time, I have become accustomed to adding a seal to my heart to lock away the pain. Just let happiness flow, just let smiles infect, just let warmth spread, why let pain overflow! This has become a habit. It's sealed, and although I can't tell whether it's sad or sad, I still know how much fermented acid is left in my heart. So I took a long walk and let the bitter juice drain out slowly. ——(Taiwan) Jian Kuan's "Snow in Spring". Reading this, I burst into tears.
