What emotion does the poem Yellow Crane Tower express?

This poem is full of scenery before writing, and lyrical after writing, which is natural. Even a generation of Li Bai, who is known as the "Poet Fairy", can't help admiring again and again, and thinks it is better to stop writing for a while. To this end, Li Bai also sighed with regret and said: "There is no good scenery in front of me, and Cui Hao wrote a poem on it!"

Yellow Crane Tower/Yellow Crane Tower

Tang Dynasty: Cui Hao

The fairy of the past has flown away by the yellow crane, leaving only an empty Yellow Crane Tower.

The yellow crane never revisited earth, there have been no long white clouds for thousands of years.

Every tree in Hanyang has become clear due to sunlight, and Nautilus Island is covered with sweet grass.

But I looked home, and the twilight was getting thicker. The river is shrouded in mist, which brings people deep melancholy.
