The storyteller called Kou Zhun "Kou Lao Xi Er". Modern people call Shanxi people "Laoer", and some famous Shanxi people are nicknamed "X Laoer", such as Yan Xishan, also known as Yan Laoer.
Therefore, storytelling takes Kou Zhun as a native of Shanxi, and Liu Lanfang always vividly imitates Kou Zhun's speech with Shanxi accent. I didn't know this was a fallacy until I read Biography of the History of Song Dynasty.
The cause of death was: 1020. In Song Dynasty, Ding Wei slandered Kou Zhun to the emperor on trumped-up charges, and Kou Zhun was exiled to southern Xinjiang, where he died. On the seventh day of leap September, Kou Zhun died in Leizhou at the age of 62.

Uncle Kou was demoted. It is said that Ding Wei and others in Song Dynasty did it behind Song Zhenzong's back. According to the Biography of Kou Shu in Song Dynasty, Kou Shu was demoted and Zhenzong was sick. He asked the people around him why he hadn't seen Uncle Kou for many days, and the officials around him didn't dare to answer the truth. On the day when Uncle Kou left Beijing, ministers were afraid to see him off because they were afraid of Ding Wei's Song Dynasty. Only Wang Shu regards "the righteousness of friends" as Uncle Kou's farewell dinner.
Li Di, who was involved in politics, was very angry. He openly claimed to be sworn to Ding Wei Song Dynasty, and even beat Ding Wei Song Dynasty with his hand. Li Jue wrote to the Emperor, denouncing Ding Wei's treachery and appealing to Kouxian for grievances. After Uncle Kou was deposed again, Ding Wei of Song Dynasty became prime minister and demoted Uncle Kou again.
In the first year of Ganxing (1022), he left Daozhou with resentment and went to work in the southern coastal city of Leizhou. After he took office, he didn't even have a decent house, but local officials and people always praised Uncle Kou as a man and took the initiative to build a house and arrange apartments for him. When he was in office, except for a few government affairs, he mainly read and interpreted the classics, wrote in his spare time and made friends. Whenever the guests arrived, he greeted them with a smile, without the appearance of a powerful official.
In September of the first year of Tiansheng (1023), Uncle Kou died of illness on a bamboo couch in Leizhou, and his wife Song Zuoqi was buried in her hometown, and Renzong allowed her to play. However, due to the limited cost, the coffin was transported halfway and the money was used up, so it had to be buried in Gongxian County, Luoyang.
In November of the second year of Ming Dow (1033), Renzong made amends for Kouxian, reinstated Kouxian's position as a teacher and Prince Lai Guogong, and presented a letter from the secretariat, saying that posthumous title was "loyal". Uncle Kou was buried.
In the first year of Emperor Yangdi's reign (1049), Renzong ordered Sun Jian, a bachelor of Hanlin, to write the Gongzhong Monument of Kou Zhong in Laiguo for Koushu, and personally wrote the word "Zhong Jing" for the first monument.
