彰化縣
In 1723, after the Zhu Yigui rebellion, an inspector official in Taiwan requested to the Qing Emperor to designate Changhua to another county magistrate and legal warden because of the increasing population in the northern part of Zhuluo County. As a result, Changhua County was created, encompassing the area of modern Changhua County, Taichung, half of Yunlin County and three townships of Nantou County. Changhua County Hall was built in the middle of the district and is regarded as the beginning of the Changhua County establishment.
