The area of present-day Huimin County was held by
Dongyi tribes during
China's
Shang dynasty before being organized as the
state of
Qi by
Jiang Ziya shortly after the establishment of the
Zhou. Following the
collapse of the
Qin, a
Qi Kingdom was reëstablished in the area during the
Chu–Han Contention and early
Han before being reorganized first as the
Jibei Kingdom and then as
Pingyuan Commandery. By the
Eastern Han, the area immediately around Huimin was organized as
Yanci County. The county seat became the capital of
Di Prefecture when it was rëestablished by the
Tang in AD643. By the late Tang, Di Prefecture made up part of the territory of the independent
Chengde jiedushis and, during the
Five Dynasties and Ten Kingdoms Era, it formed part of the short-lived
Kingdom of Zhao. After 1373, the area was administered as
Le'an Prefecture. ==Geography and climate==
