[10] That city had been in Hebei's Yu County,[11] but it was used for a series of petty states and appanages during the Warring States, Eighteen Kingdoms, and Han which spread the name into Shanxi's Yanmen and Yunzhong Commanderies.

[14] Its seat was at present-day Daixian,[14] which was known as Guangwu until 598[5] and then as Yanmen when its surrounding county was renamed due to the Chinese naming taboo.

During this period, the seat at Daizhou administered a prefecture covering what are now the counties of Dai, Wutai, Fanshi, and Yuanping.
