Historical evolution of Chengbei town

According to the examination, the north of the city belonged to Fengcheng and Fuzhou in ancient times (including Fuchuan and Zhongshan today). In the Ming Dynasty, it was transferred to Jiudu, and Mashan Regiment was under the jurisdiction of the Republic of China. Later, Chengbei Township was established from Chaodong District, and later changed to Town. Around 2 13 BC, Zhao Pi, a veteran of Qin Jun who was stationed in Jiuyi Zhu Meng Fortress, sent someone to build an ancient post road from Qingshankou (now Gepo) Post Station on Qinxin Road to Yuankou, Hunan via Niu Niu Ping, Chengbei and Laochao Cave. Up to now, there are still piers and some ancient roads at the west entrance of Sichuan. In the third year of Emperor Kangxi of Qing Dynasty, Guangxi was stationed in Fengxi (now Fengxi) Bridge, Dafu, and PingYuefu Patrol Road (the fourth-level official) was stationed in Dazhaitou, Shilong, and fought fiercely with Liao Wendan in Baizhuwo for more than two months. The battle of Baizhuwo was also famous in the Qing Dynasty.
