Li Yan (simplified: 李严, traditional: 李嚴, pinyin: Lǐ Yán), courtesy name Zhengfang (正方 Zhèngfāng), was a general and minister of Shu Han. He had served Liu Zhang in Yi Province and surrendered to Liu Bei during the Conquest of Yi Province. Liu Bei made him General Who Establishes Enterprise. In 214 he was one of the officials (with Zhuge Liang, Fa Zheng, Liu Ba, and Yi Ji) who established the Shu Code (蜀科). He later became a senior general and Chancellor. Liao Li resented being ranked below him. When Zhuge Liang campaigned in the north, Li Yan was responsible for supply from Hanzhong; he failed to deliver grain and sent a false report that the campaign should withdraw. When the truth came out, Zhuge Liang memorialised and Li Yan was stripped of rank and exiled to Zitong. He died there in 234.
Biography
Service under Liu Bei and Shu Code
Li Yan was from Nanyang and had served Liu Zhang. When Liu Bei took Yi Province, Li Yan went over to him. He was made General Who Establishes Enterprise and joined Zhuge Liang, Fa Zheng, Liu Ba, and Yi Ji in drafting the Shu Code to tighten laws and administration.
Rise and fall
Under Liu Shan, Li Yan was promoted to senior military and civil posts (Chancellor, General Who Inspires Awe). He was entrusted with supply for Zhuge Liang’s Northern Expeditions. In 231 he failed to get grain to the front and sent a message that the army should withdraw (claiming the emperor had ordered it or that supply was impossible). When Zhuge Liang withdrew, Li Yan pretended the grain was coming and said the retreat was strange. Zhuge Liang produced Li Yan’s letters; Li Yan confessed. He was demoted to commoner and exiled to Zitong. When Zhuge Liang died in 234, Li Yan expected to be recalled; when no recall came, he died of illness.
Legacy
Li Yan is remembered as a capable official who helped establish Shu’s legal system but whose deception over supply led to his fall and exile.
