Jiaocheng belonged to Jin in the Spring and Autumn Period and Zhao in the Warring States Period. Sui was named Jiaocheng because the county ruled the intersection of Fenkong and Hull River (so it was ruled in today's ancient Taiyuan). During the Tianshou period of the Tang Dynasty, the county was moved, and the county names remained unchanged throughout the ages. 1958 was merged into Fenyang County, and Jiaocheng County was restored the following year.

The base of Jiaochengshan Rebel Army was located here in the late Ming Dynasty. 1664, Li Zicheng crossed the Yellow River eastward, where he joined forces with Jiaocheng Army. On this basis, he broke Fenzhou, fell into a meander, quietly and happily fought a battle, captured Taiyuan, and captured Zhu Qiujia, the king of Jin. The mountain, located 6 kilometers east of Gudong Road, is named after the cemetery of his grandfather Kim Dae-fu and his second son Huyan.
