What is the author's mood in Nanting?

Meet in Nanting —— Tang/Xu Hun

The water in the city is connected, and the tide is surging wild boats.

The bird is surprised, the fruit falls, and the turtle is green.

A thousand rolls of white paper and a glass of cinnabar wine.

Nanxuan shed tears, not looking at Yantai.

Analysis: The waves in the urban waterfront are spectacular, disturbing the birds in the mountains, and the fruits on the fruit trees fall to the ground. The tortoise pushed the duckweed away and let it play freely. I was moved to tears with thousands of books in my hand and a glass of wine in my hand, but I didn't look at Yantai.

Xu Hun was an official poet in the Tang Dynasty, and his poems were mainly nostalgic and idyllic.
