You hide the smile at the corner of your mouth, but you can't get rid of the melancholy on your brows. It's just the truth that can't be concealed, burying your helplessness in my heart. I put sorrow on the wound, but it can't heal the sadness that will always accompany life. It's just the emotions that can't be expressed that will engrave my words on your vicissitudes. In these years, times are changing, and so are concepts. Aesthetics is the fastest, most frequent and most powerful thing, spreading like the flu in an instant. When you wake up the next day, you may find that some people wear cotton shoes when the temperature is 30 to 40 degrees Celsius; some people wear miniskirts during the ice and snow season. Not to mention that, the strangest thing is the bunch of hair on the head. Walking in the streets and alleys, I saw a "young lady" with long flowing hair who seemed much taller than before. When I turned my head, I saw that she had a beard. And the one with long hair, or even no hair at all, might be a woman.
