Tang Wenzong three years (838). Li Shangyin, a famous poet in the late Tang Dynasty, went to Jingyuan as an aide and married Wang Maoyuan's daughter. Anding City, located in the northern part of Jingchuan County, Gansu Province, is the residence of Jingyuan envoy of the Tang Dynasty. Li Shangyin was helped by Ling Huchu and his son, who were important tasks of the Niu Party, while Wang Mao Yuan was regarded as a figure of the Li Party. Therefore, this year, after Li Shangyin was admitted to Jinshi, he was rejected by the clique forces, unfortunately lost the election, and returned to Jingyuan in frustration. This is the season when spring breeze blows willows and willows dance. The poet climbed the Anding Tower, the head of Jingyuan ancient city, and looked from a distance. Seeing the chaos of state affairs and rampant corruption, people with ideals and talents can't display their ambitions, and they can't help but feel infinite feelings of losing their country and their lives. Therefore, the poet wrote these seven methods into the "Stability Tower".
