I asked you how worried you were. It was written by Li Yu, queen of the Southern Tang Dynasty during the Five Dynasties and Ten Kingdoms period. Li Yu, the sixth son of Yuan Zong in the Southern Tang Dynasty, was born in Pengcheng (now tongshan district, Xuzhou, Jiangsu) and Jinling (now Nanjing, Jiangsu), the last monarch of the Southern Tang Dynasty. The definition of this poem is when the year ends and how much you know about the past. Last night, there was a spring breeze blowing in the small building. How can I bear the pain of thinking of my hometown on this empty night? Carefully carved railings and jade steps should still be there, but the people I miss are aging. Ask me how much sadness I have in my heart, just like this endless spring water rolling east. Smoke and rain lock the heavy building: the smoke covers the layers of pavilions, describing the weight of the soul, borrowing things to describe people, and not seeing Toya's inescapable situation. The word lock is a good use, which is a metaphor for emotional shackles and troubles.
