#PI#On the morning of the Dragon Boat Festival in 2025, light rain patters down, and the air is filled with the unique freshness of the festival.

In May, when the summer heat begins to awaken, all things stretch and breathe between the damp and the warmth, and our hair subtly senses the prelude to this summer.
