The creation time of 'Old Stone in the Glass World' is in the winter of 2023. Snow fell early this winter, and in reality, the glass world has no red plum blossoms, let alone plum fragrance. I still remember the pain of the cold wind blowing on my face while riding a bike, the dimly lit miscellaneous room, and the stiff fingers exploring a space on paper that 'falls outside of four o'clock'. The manuscript progresses a little bit every day, and the chill is further away from me.
