I Strayed into the Depths of Peach Blossoms

When I was young, for some unknown reason, I accidentally entered the depths of the peach blossoms. It was said to be the depths of the peach blossoms, but in fact, the depths of the peach blossoms were just the tip of the iceberg. I didn't know the details at the time, and I couldn't remember them. By the time I came out of the depths of the peach blossoms, it was already a hundred years ago. What happened in these hundred years? Why do I feel like only ten days have passed, but a hundred years have passed in the blink of an eye? Maybe I was still young at the time, but when I think about it now, I slap my thigh with regret.
