History of Guzhen Guzhen area was developed earlier. It was the land of Huaiyi during the Xia and Shang Dynasties. Counties were established successively from the early Han Dynasty to the third year of Xianheng in the Tang Dynasty (672) when it was completely abandoned. In the early years of the Western Han Dynasty, Guyang County was established one kilometer south of the current county (south of Huihe River and west of Railway). It was named because it was located in the Yangtze River. Gushui is now the Huaihe River. In the 13th year of Jianwu in the Eastern Han Dynasty (AD 37), Cen Huai was granted the title of Marquis of Guyang. During the Song and Qi Dynasties in the Southern Dynasties, it was the county seat of Yangping County. In the Northern Dynasties and the Northern Wei Dynasty, it was changed to Guyang Town in the seventh year of Taihe. It was called Xigu Town in the Northern Song Dynasty and Xigu Town in the Jin Dynasty. During the Ming and Qing dynasties, an inspection department and flood control department were set up. Guzhen Post was the largest post station on the Beijing-Ningbo ancient road between Fengyang and Xuzhou. Since ancient times, Guzhen has been at the center of north-south transportation and has always been a battleground for military strategists. In the fifth year of Emperor Gao of the Han Dynasty (202 BC), Chu and Han fought a decisive battle in Guzhen. In the 13th year of Jianwu of the Eastern Han Dynasty (AD 37), Xu Shen, a famous Confucian scholar and ancient philologist, served as the head of the Ministry of Education here. During the Jian'an period, Cao Cao set up camp in what is now Cao Laoji to compete for the Jianghuai River. In the first year of Longxing in the Southern Song Dynasty (1163) ), Huaixi's recruiting envoy Li Xianzhong defeated the Jin soldiers in Dougou. In the late Qing Dynasty, the Nian Army fought hard here for many years. In 1911, Sun Yat-sen's Northern Expeditionary Army defeated the Qing army in Guzhen. In 1925, Sun Chuanfang, the Zhili clique warlord, gathered the coalition forces of five provinces and fought fiercely with Zhang Zongchang, the Fengcian warlord, in Guzhen. During the Anti-Japanese War, Japanese imperialism had been entrenched in the town for eight years, and the area was a battlefield fought over by the Communist Party, the Kuomintang, and the Japanese and puppet armies. During the Huaihai Campaign, Guzhen was a strategic location for the People's Liberation Army to block the Kuomintang's southern reinforcements. After the victory of the Huaihai Battle, this area became an important route for the People's Liberation Army to cross the river southward. In July 1985, the Haocheng Collection in our county was confirmed as the Gaixia Site, and was approved by the Provincial People's Government as a provincial key cultural relics protection unit in July of the following year.
