What is the origin of Heze place names?

Heze, formerly known as Yin Ji and Cao Zhou, is 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. It is located between 34 39' ~ 35 52' north latitude and114 45' ~116 25' east longitude. North-south length157km, east-west width140km, total area12238.62km2. ..

Heze was originally a famous Zeguo in the pre-Qin period, saying, "Guide Heze and be guarded by Mencius". In the northeast of Dingtao, it is a natural lake where Jishui (rivers, Huaihe River and Jihe River are also called the four major blasphemies in the world) meet. In the Tang Dynasty, it was renamed Longchi, also known as Jiuqingbo, and in the Qing Dynasty, it was called Xiayue Lake, which dried up and disappeared. Today, the Pi River depression and imitation mountain depression of Dingtao are intended to be its remains.

Legend has it that Heze is a place where Yao raises dragons. After Yao's old Zen position was ceded to Shun, he returned to the pottery (now Dingtao) that was sealed when he was young, and built a "Yougong" (now Township Temple) not far from Du Qingling Terrace (Yao Mu Ling) to settle down. In order to make the wise emperor who worked so hard for the people live a long life, Shun prepared all kinds of flowers and animals for him and ordered Dongfu to pay tribute to the dragon in Heze. Dongfu is good at raising dragons. When he whistles, the dragon will fly to him. Some of them came out from the bottom of the water, and some jumped out of the air. They are colorful, lively and lovely. Yao often comes here to watch games.

The administrative division name of Heze is "In the 13th year of Yongzheng (1735), Cao Taishou was promoted to the government, and the attached country set up Heze County", so Heze was named after the water, which has been used three times since the city was changed.

Heze, the hometown of Yao and Shun, is the birthplace of Fuxi Mulberry. It is first the capital of Shang Tang, then the territory of Cao, and then the Cao Zhou area. In ancient times, it was a natural lake, where Ji and Shui merged and merged to connect Ji Gu and Surabaya. Because there are Heshan in the south and Razer in the north, it is named "Heze". In the Tang Dynasty, it was renamed Longchi, also known as Jiuqingbo, and in the Qing Dynasty it was called Xiayue Lake. The present site is located in the southeast of Mudan District, Heze City 15km. The county with Heze as its place name began in the early Qing Dynasty. According to the Records of the Government in the Twenty-first Year of Qing Qianlong, in the Qing Dynasty, in the thirteenth year of Yongzheng (1735), it was promoted to the government, with Guo County attached, and its territory was still the old state, hence the name Heze.
