Jiāoxī
Jiaoxi was the county at the seat of Jiaozhou in the Yuan period, near the northwestern side of Jiaozhou Bay. The local gazetteer records the capture of Jiaozhou by Mao Gui's Red Turban forces in 1357 and a move of the prefectural seat eastward to a new inner city in the same year.
In 1369 the Ming abolished Jiaoxi County and placed its territory directly under Jiaozhou, which continued to supervise Gaomi and Jimo counties. The inner city was faced with brick and stone in 1375, and the local chronology records renewed dredging and locks along the Jiaolai waterway in 1542. Later cultural institutions included Jiaoxi Academy, established in 1786.
