Gaocheng, called Gaocheng in ancient times, was a man in the Spring and Autumn Period. After the demise of Qi, Qi returned to Qi. In the Western Han Dynasty, Gaocheng County was established here. In the Eastern Han Dynasty, it was merged into Xu Zhu County and reduced to Gaocheng Pavilion. "Continued Archaeological Records of Shandong Province" quoted "Geographical Customs" as saying: "There is Yucheng Pavilion in the east of Xu Zhu County, so the county is also. It is Yucheng Pavilion, that is, Yucheng County has been reduced to a pavilion. " Jin Huidi set up Pingchang County here. During the Tianbao period of the Northern Qi Dynasty, it was changed to Langya County Administrative Office.

From the analysis of the relics exposed in the old city, the ancients once lived here and made contributions to the development of history and culture. To study the decline of primitive society, the formation of slave society and the separatist regime of feudal society, we can learn from Old Town. Later, when the ancestors built the village, in order to commemorate the prosperity of Qiaocheng in the past, the word "Qiaocheng" was never forgotten. The villages west of Qiaocheng Old Town were originally called Qiaoxi and later Xiqiao, such as Li Jia Xiqiao and Liu Jia Xiqiao. The south of the old city is called South Bridge, and the north is called North Bridge (Xiaobeiqiao Village, shagou town). During the "People's Commune" period, several natural villages near the old city were Gaocheng Brigade. It is located about 30 kilometers southwest of Anqiu City and about 200 meters east of Lijiachibu Village in shagou town.

Li Yuan, a native of Zhu Xu (now Red shagou town) in the Three Kingdoms period, was a famous Confucian at the end of the Han Dynasty. When I was a child, my family was poor and my parents died early. I learned the classics from my neighbor's teacher, and I can recite the Classic of Filial Piety and The Analects of Confucius in one winter. Later, he traveled around the world, talking about rites and music, poetry and books, and talking about doors.

There are many people. He was recruited by the county as the master book and planner. During the Yellow Scarf Uprising in the late Han Dynasty, he and his good friend Guan Ning stayed in Liaodong for more than ten years. There are many tigers in Liaodong, but there are no tigers in the village after Liyuan went. Tang gaozu once picked up a string of copper coins by the roadside and tied them to branches. More and more people tie them up instead of taking them away. He asked the reason and called the tree a "holy tree". Tang gaozu was afraid that it would gradually become a bad habit, so he put away his wealth as a social sacrifice after the sacrifice. When Cao Cao was a mediocrity, he set up the East Pavilion to offer a drink. A daughter died young in the pear garden, and Cao Cao's son Cang Shu also died. He wants to be buried together. Liyuan insisted on politely declining, saying, "It is indecent to be buried together." Cao Cao no longer insisted. Another day, Cao Pi hosted a banquet for guests and said, "Your father and your father have their own illnesses. One pill can save one person. Should we save you? " Father? "All the guests are talking about it, but they can't agree. Only Li Yuan kept silent. Cao Pi also named Li Yuan for an answer. Li Yuan was furious and said, "Father." Xelloss is no longer embarrassed. Li Yuan and Zheng Xuan are both masters of Confucian classics, but they belong to different schools. According to the Records of the Three Kingdoms and Biography of the Great Plains, there are hundreds and dozens of disciples in the Great Plains. At that time, Zheng Xuan interpreted the classics with erudition, so elegant people gathered; Originally, he was also innocent with lofty ideals and indifferent to his own ambitions. He had no choice in his mouth or in his body, so the hero went to Yan; At that time, it was clear in the sea that Qingzhou had Taihe Zheng Zhixue. "Visible tang gaozu's position in the classics, can be compared with Zheng Xuan. Hua Xin, Li Yuan and Guan Ning are friends, and the time number is "Yi Long", with Hua Xin as the leader, Li Yuan as the belly of the dragon and Guan Ning as the tail of the dragon.
