以下是这首诗的英文翻译：

"Seeing Meng Haoran Off to Guangling from the Yellow Crane Tower"

The solitary sail fades into the blue sky vast,

Only the Yangtze flows to the horizon boundless and fast.

At the Yellow Crane Tower I see my friend depart,

With spring blossoms on the river, we part heart to heart.

This translation aims to capture both the imagery and emotional depth of the original Chinese poem. It reflects the scene where the poet watches his friend's boat disappear into the distance while the mighty Yangtze River flows endlessly. The imagery of the solitary sail and the endless river symbolizes the impermanence of life and the inevitability of separation.

Through this translation, readers can appreciate the beauty of the original work and the universal theme of friendship and loss that transcends language and culture.
