Third, the original poem
Two Storms on November 4th (Song: Lu You)
I lay sprawled in my lonely country, not feeling sad about my situation, but thinking about defending the frontier of the country.
The night will be over, I lie in bed listening to the sound of wind and rain, in a daze in my dream, riding an armored horse across the frozen river to the northern battlefield.
Interpretation: I am lying upright in a lonely and desolate village, not feeling sorry for my situation, but thinking about defending the country. As the night drew to a close, I lay in bed and heard the sound of wind and rain. I dreamt in a daze that I rode an armored war horse across the frozen river to the northern battlefield. )

Lu Yousheng was deeply influenced by family patriotism when he was a teenager. When I was in Song Gaozong, I took the does exam, but my career was not smooth because I was rejected by Qin Gui. Song Xiaozong was born a scholar after he acceded to the throne. He used to be the master book of Ningde County, Fuzhou, the official of deleting government decrees, and the judge of Longxing House. Because he insisted on resisting gold, he was repeatedly rejected by the Lord and factions.
After Song Guangzong succeeded to the throne, he was promoted to Doctor of Rites and Reviser of History Museum. Soon after, he was dismissed from office and returned to his hometown for "mocking romantics".
Lu You lived in Yin Shan for a long time, and The Storm of November 4th was written in three years (1 192) when Lu You retired to Yinshan.
Poems show that Lu You devoted himself to the war of resistance and served the country. However, the poet was ambitious, but he was not valued by the court. He can only "lie in a lonely village" and pin his ideal of restoring the Central Plains on his dreams. Deep and tragic feelings condensed the poet's patriotic passion.
