What's the meaning of the poem "The fence door feels dawn and welcomes the cold in autumn night"?

Autumn night, when it was dawn, I walked out of the gate, and suddenly there was a cool breeze blowing through the street, which made me feel sad, so I wrote this poem.

The Feeling of Going Out of the Hedge Gate in Autumn Night is the work of Lu You, a poet in the Song Dynasty.

Original text:

3. East of Wan Li River flows into the sea, reaching a height of 5,000 meters.

The adherents wept in the dust and looked south to Julian Waghann for another year.

Translation:

The Yellow River, which is long in Wan Li, flows eastward into the sea, and Huashan Mountain, which is 5,000 meters high, goes straight into the sky.

Under the oppression of the conference semifinals, the tears of the Central Plains people have run out, and they look forward to Julian Waghann's Northern Expedition year after year.

Extended data

Start with the sentence "Three Wan Li rivers and seas, five thousand mountains climb skyscrapers". Two words horizontal flat vertical, the victory of the northern Central Plains half of China is obviously abrupt and boundless. However, great rivers and mountains, trapped in which the enemy, people feel extremely indignant. The artistic conception of these two sentences has been expanded and deepened, which is still a neat problem.

As soon as I wrote the next two sentences, I suddenly felt that the situation was prominent and the poetic realm was developing in a far-reaching direction. The word "exhausted tears" is full of twists and turns and contains infinite bitterness. Tears have been flowing for more than 60 years, and they are long gone. But even if "the eyes are dry and the blood is finally seen", those adherents who are worried about the country and the people still look forward to the south sky; The dust raised by the Golden Horse team kept them looking forward to Julian Waghann.
