Beidou was previously known as Po-tau (寶斗; Pe̍h-ōe-jī: Pó-táu), a harbor on the branch of Zhuoshui River and engaged trading with mainland China. As the harbor was an important site of southern Changhua County in the late Qing era, the town was surrounded by fences and had defensive walls. In 1738, the first downtown street named Shezi Village was built in the southern bank of Dongluo River. In 1806, houses and fields along the downtown streets were all ruined due to the battle between immigrants from Zhangzhou and Quanzhou. In 1821, Shezi Village was rebuilt in the Baodou Village at the riverside.[1]
