Heze used to be a natural ancient river, where Ji and Shui meet and come out together, connecting the two major water systems of Guji and Surabaya. It was renamed Longchi in the Tang Dynasty and Xiayue Lake in the Qing Dynasty. In the 13th year of Yongzheng in Qing Dynasty (1735), it was promoted to the government and became Guo Wei County. Because there is "Heshan" in the south and "Razer" in the north, it is named Heze.

Heze, a prefecture-level city under the jurisdiction of Shandong, is the peony capital of China, which was called Cao Zhou in ancient times. Located in the southwest of Shandong Province, at the junction of Shandong, Jiangsu, Henan and Anhui provinces, it is adjacent to Jining City in the east, Xuzhou City in Jiangsu Province and Suzhou City in Anhui Province in the southeast, Shangqiu City in Henan Province in the south, Kaifeng City and Xinxiang City in Henan Province in the west and Puyang City in Henan Province in the north.

Heze has developed in recent years.

In the past five years, Heze has been included in 360 provincial key projects, such as major provincial projects, optimization of new and old kinetic energy, and short board strength, ranking first in the province for five consecutive years, and the amount of bond funds approved ranks among the top in the province. It can be said that key projects are like a powerful engine, and the accumulation in the past five years has led Heze to achieve a gorgeous butterfly change.

Lunan high-speed railway has opened a new vein, Peony Airport has inserted new wings, beach relocation has opened a new life, the construction of modern medical port has written a new chapter, and the development of high-end chemical industry has entered a new stage. During the five years from 20 17 to 202 1, Heze achieved historic breakthroughs in many fields, and the total economic output achieved a wonderful leap from "the countdown of the whole province" to "the middle reaches", which was called "Heze phenomenon" by the outside world.
