Due to repeated floods, the town site is no longer visible, and it is still called the old county set.

During the new dynasty, steroid county was renamed "Jiaxu".
The Eastern Han Dynasty belonged to Chenliu County. In the second year of Emperor Zhang Zhaodi's reign (AD 77), he traveled to steroid county in the east. He said to Japan that "Chenliu steroid county has a bad name ....., taking its honor to test the righteousness of Wu Wang, and changing steroid county to Kaocheng county."

From the Han Dynasty to the early Yuan Dynasty, the governance of Kaocheng County has not changed. After the Yuan Dynasty, due to the flood of the Yellow River, the administrative offices of Kaocheng County moved frequently. In April of the 25th year of Yuan Dynasty (A.D. 1220), the river burst its banks and entered Kaifeng, flooding the whole city. In order to avoid the river disaster, what does the county magistrate Li Maozhi want (near Wangqiaoji in Minquan County today)?
In the 23rd year of Hongwu in Ming Dynasty (A.D. 1390), the county seat was flooded again, and "Yang Xianzong, the magistrate of a county, moved to Jiangshang Tomb Shop" (Jiangshang Tomb Shop is located in Litang Township, Minquan County). In the second year of the Ming Dynasty (A.D. 1437), Kaocheng was flooded again, and "Zhengdao County moved to the old city" (the old city is now Beiguan set in Minquan County).
In the forty-eighth year of Qing Qianlong (AD 1783), in March, Kaocheng County ordered Lei Xun to build a new city in Guyang. At this point, the Kaocheng County Government was established in today's lankao county.
From the Qianlong period of Qing Dynasty to the 17th year of the Republic of China (1928), Minquan County had no county administration, and its territory belonged to Kaocheng County, Sui County and Qi County.
On March 8th, the Republic of China 17 (1928), Liu Zhenhua proposed and was approved by Feng Yuxiang, chairman of the Henan provincial government, to delimit three districts of Sui County (including Beiqili, which belongs to the old experimental city, namely Dafanji, Wangqiaoji, Chendianji, Jiuxian Village, Diesel Ji Fang, Linqikouji, etc.) and some districts of Sui County.
1949, kaocheng county was moved from guyang town to Zhang Jun tomb town.
1954, Lanfeng and Kaocheng counties merged and were named lankao county, named after the initials of the two counties. In the same year, Beiguan, Chumiao and Chengzhuang, which were originally under the jurisdiction of Kaocheng County, were placed in Minquan County.

Kaocheng County is near the Yellow River, which has been flooded many times in history and moved to the city six times. According to the above, it can be seen that Kaocheng County of Sui State in Jin Dynasty is located in the east of Minquan County, Henan Province, more than 40 kilometers away from Guyang Town (now Lankao, Henan Province), and it was under the jurisdiction of Kaocheng County after the migration of Qing Qianlong.
