Lying in the midnight listening to the wind and rain, the Iron Horse Glacier dreams.
chasing the sound and chasing the water through the hibiscus, you can't drop it, it's in the flowers and clouds.
This poem describes Li Bai's mood when he was walking along the Shu Road. He was lying in bed at night listening to the sound of wind and rain, thinking of his iron horse dreaming of himself in the cold river, which made his mood heavy. He is eager to follow the current and cross the hibiscus flowers, but he can't, so he can only wander among the flowers and clouds.
