The Qing Dynasty took rule over Taiwan in the 22nd year of the Kangxi reign (A.D. 1683), and the next year Taiwanfu, the Qing Dynasty political administration in Taiwan, was established, consisting of 3 counties: Taiwan, Fengshan, and Zhuluo counties. At that time, the district of Changhua was under the rule of Zhuluo County.

The Changhua district, however, had it all over the three counties in the majesty of its mountains and rivers, in the richness of its natural resources, in its large population density, and in its highly literate milieu.

In 1723, the first year of the Yongzheng reign, Wu Dali, the inspector official in Taiwan then, proposed to the throne, "As in the northern part of Zhuluo County lives together the Chinese people and other races, Your Majesty are respectfully requested to designate another county magistrate and legal warden to that district…"

As a result, Changhua County was established, its reaches stretching from the northern boundary of the Huwei district to the southern border of the Dajia district. And the name, "Changhua," means "manifestation of royal civilization" in its literal meaning; its formal wording is "manifestation of the majestic Emperor's civilization spreading over to the corner of the seas."

Changhua County Hall was built in the mid of the district, and it is regarded as the beginning of Changhua County establishment.
