Six thousand years ago, the Yan Emperor Zhu Xiang's family founded the capital and buried it in Zhecheng, where the Zhu surname originated. In the Qin Dynasty, a city was built and a county was set up. It was named "Zhe County" because of the circulation of Zhe Valley and the clumps of Zhe trees on both sides of the city. Since ancient times, Zhe silk is abundant, which belongs to Chen County and Dang County respectively. The county seat is located in Chen County. In June of the third year of the Republic of China (1914), Zhecheng belonged to Kaifeng Road, Henan Province. After liberation in 1949, Zhecheng belonged to Shangqiu District of Henan Province. In 1997, a prefecture level Shangqiu City was established, and Zhecheng belongs to Shangqiu City.
