Cao Xuequan (1574- 1646), an official, scholar and bibliophile in the Ming Dynasty, was the first of the ten sons in central Fujian. Words can be remembered, and words respect life. It's called Yanze, also called Shicang layman and Xifeng layman. It comes from Tang Hong Township, Houguan County, Fuzhou District, Fujian Province. In the twenty-third year of Wanli, he was a scholar and served as a right-wing political representative in Sichuan, a provincial judge and a counselor in Guangxi. He was illegally removed from his post and lived at home for 20 years because he wrote that unofficial history offended the Wei Zhongxian Party. When the Qing army invaded Fujian, Cao Xuequan bathed in fragrant soup, tidied up his clothes, hanged himself at the home of Xifeng pear, and left a pair of desperate couplets before he died: "A pen before death, a rope after death." Another story says that he hanged himself in Yongquan Temple in Gushan. After Cao Xuequan's death, his home was copied by the Qing army, his family was arrested and his books were taken away by the Qing army. In the 11th year of Qing Qianlong (1746), that is, one hundred years after Cao Xuequan's death, the Qing government recognized him as "Loyalty Festival".
Cao Xuequan studied literature, poetry, geography, astronomy, Zen, temperament and a hundred schools of thought all his life. He is particularly good at poetry, and writing lyric poetry is his specialty. He wrote more than 30 books in his life. It is said that Cao Xuequan's Song Zhentu hangs in the lobby of the "Seventy-two Peak Building" of Lin Zexu's Fuzhou Mansion. Step by step, wash the axis of spring poetry, write like flowing clouds, cadence, get the fashion of Jin and Tang dynasties, and show the gentleness and calmness of a gentleman.
