Changhua is embraced by mountains to the east, south and north, with the peak of Bagua Mountain (Baguashan) towering above them all and the Taiwan Strait to the west. The resulting warm climate and moderate rainfall provide an ideal environment for farming, earning Changhua the nickname of "Taiwan's granary." The county was originally known as "Banxian," after a local indigenous tribe. During the Yongzheng period of the Qing dynasty (1678~1735), this region was settled by Chinese immigrants from southern Fujian.
