Help me analyze and appreciate this poem by Wang Wei?

Send kang taishou

Cangjiang at the door, Yellow Crane Tower by the river. Zhu Lan will be pink, and the river will reflect.

The cymbals blow the summer mouth, making the monarch above. The door hides the maple bank, and the officials wait for Luzhou.

What's the difference between Linchuan County and Xianhou?

The expression is simple, just like two good friends are leaving and Wei Wang is saying goodbye. The first four sentences describe the scenery, but there seems to be no trace of sadness. It's just that there is a lot of money in this turbulent water. When Qu Yuan was exiled here, he wrote a swan song, "I am alone in the turbid water in the world, and everyone is drunk and I wake up alone." Wang Wei obviously has no artistic conception of Qu Yuan in this poem, because Qu Yuan is in exile and Wang Wei is giving people away.

The Yellow Crane Tower stands by the river, with red railings echoing the white walls, and the mutual reflection of the river. Obviously, he wrote about scenery. Poets in the Tang Dynasty preferred the Yellow Crane Tower, so the first four sentences of this poem describe the landform and surrounding scenery of the Yellow Crane Tower.

Combining the last six sentences, this poem was actually said by Wang Wei and Kang was listening.

When I went to Linchuan County, it was Brother Kang who took care of me.
