During the Qing dynasty, Tirosen was governed as part of Taiwan Prefecture in Fujian under Zhuluo County and the city was renamed Kagee in 1787.

In 1998, Taiwan Province was streamlined and Chiayi City has been governed directly since then by the Executive Yuan.

The city is known for Alishan National Scenic Area and warm humid subtropical climate in the summer months.

Because of the choice of the characters, it has been mistakenly suggested that the origin of the name came from the expression "mountains surrounding the east".

[6] The place was north of Mattau (modern-day Madou, Tainan) and south of Favorlang (Huwei, Yunlin).

In 1661 (the 15th year of Yung-Li, Ming dynasty), Koxinga defeated the Dutch based in Taiwan and founded the Kingdom of Tungning.

In 1683, when Qing rule began, the island was governed as Taiwan Prefecture under the administration of Fujian Province.

The four gatehouses were named: "Chin Shan" (襟山) for East, "Tai Hai" (帶海) for West, "Chung Yang" (崇陽) for South, and "Kung Chen" (拱辰) for North.

In 1786, the Lin Shuangwen rebellion was an attempt to siege Tsulosan but failed to overcome the defense of the inhabitants.

[9] In looking over some of my more recent Notes, it seems impossible to make the foregoing references to Ka-gi without adding a few words about that dreadful earthquake which devastated the region in March 1906.

I was there soon after, and had a profound feeling of sadness on seeing whole streets covered with fallen beams and other debris ; on seeing, too, so many traces of the awful suffering on every side.

Within Ka-gi city, and a limited area around, 1,216 persons were suddenly thrust out into the eternal world.

Many of the narrow escapes and calamities were very affecting ; particularly that of our blind evangelist Toa-un, who ran out of doors with his wife as the shaking began.

The demented mother, however, could not bear the thought of her two helpless young children being left behind, and she darted in to rescue them, when my poor blind pupil became childless and a widower in an instant of time.

No sooner had the Governor-General at Tai-pak received telegraphic information of the magnitude of the calamity, than instructions were issued for a large company of surgeons, nurses, and assistants to proceed at once to Ka-gi.

Wide hospital-sheds were erected without delay, and the work of relief was carried on with a rare amount of self-denial and promptitude.

Even already, the city has lost much of its most desolate appearance, and the projected improvements give promise that it will have a more attractive look than ever.

In early March, local militas surrounded the Shueishang Airport and fought against the KMT military.

[15] Chiayi City is located on the north side of Chianan Plain, south west of Taiwan Island.

[21] And in 2022 Taiwanese local elections, Chiayi City re-elected Huang Min-hui of Kuomintang to be the mayor.

The program is expected to produce 3.55 million kWh of electricity annually and to help reducing carbon emission by 1,700 tonnes.
