Liu Erzhi, a native of Chongqing, Sunyang and Suike, (1579— 1632). A native of the southeast corner of Ye County Chengguan (now the southeast corner of Laizhou Town), he was a famous calligrapher in the late Ming Dynasty and a right assistant minister from the official to the household department.
The teenager was born in a poor family, lived in a stone house in the Hongmiao Temple in Dazeshan, studied hard, and had no money to buy paper and collect persimmon leaf books. Later generations once praised: "waving Ozawa dragon and snake dance, picking persimmon leaves in the empty mountain." After calligraphy became famous in Beijing and the imperial court, there was a legend of "flying pens to fill in dots". Wrote the plaques of the three halls of the Forbidden City: Hall of Supreme Harmony, Hall of Zhonghe and Hall of Baohe. In the thirty-eighth year of Wanli (16 10), he was a scholar, and later he was promoted from xian county to suggestion. Because he did not attach himself to eunuch Wei Zhongxian, he was falsely accused of being a "traitor" and dismissed from office. Chongzhen was appointed as the suggestion, and wrote to arrest Wei traitors, Liu Ruoyu,. Later, he was appointed as Zheng Tong of Dali, and was promoted to the right assistant minister of the Ministry. Kong Youde mutinied around Lai, and Liu Chongqing went to the desert three times. It is clear that the important geographical location of Laizhou and the fall of Laidi will lead to serious consequences such as "North China" and "nothing to say in the world". He denounced the "carefree" of "the teacher who saved the drowning and the burning", prepared a heroic scene in which the army and the people fought bloody battles to defend the isolated city of Laizhou, and asked the emperor to adjust the customs to help Laizhou quickly. In the end, the Ministry of War was strongly supported by the Lord, and Liu Chongqing fought hard for the first world war, depressed and resentful. He died in the fifth year of Chongzhen (1632) on the third day of July at the age of 53.
