The poem "夢(mèng)江南" can be translated as "Dreaming of the South of the Yangtze River" or "Dreaming of Jiangnan." It was written by the Tang Dynasty poet Wen Tingyun. The poem expresses the poet's longing for someone who is far away. The poet describes standing alone on a high building, watching countless boats pass by on the river. However, none of these boats carry the person he longs for. As the sun sets in the west, the poet is filled with sadness and the river water flows slowly. The poet's heart is broken, and he cannot bear to look back at the White Pingzhou Island in the river. The poem is written in a beautiful and melancholic style, capturing the emotions of longing and heartbreak.
