From a supreme emperor, he became a prisoner and naturally lived a life of humiliation and tears. Li Yu, who knew rhyme well and was skilled in all kinds of poems and songs, often wrote and sang poems to express his longing for his former life as an emperor and his sadness and anguish for his present cage-like life. In 978 A.D., the third year of Li Yu’s imprisonment, he looked up at the moon on the mid-autumn night of that year and couldn’t help but feel the hatred of his fallen country. How much of the past is known. Last night, the east wind was blowing again in the small building, and the old country could not look back at the bright moon.
