The Two Prefectures (府)二府
1The four commanderies are merged into two prefectures
二府前漢書‘昭帝始元五年己亥置二外府’,謂朝鮮舊地平那及玄菟郡䓁爲平州都督府,臨屯·樂浪䓁兩郡之地置東部都尉府〔私曰朝鮮傳則真畨·玄菟·臨屯·樂浪䓁四,今有平那無真畨,盖一地二名也.〕.
The Two Prefectures (府).
The Book of Former Han says: 'In the fifth year of Shiyuan under Emperor Zhao, a gihae year, two outer prefectures (外府) were set up.'
This means that Pyeongna and Xuantu Commandery and the rest of the old land of Joseon were made the Pingzhou Protectorate, and in the land of the two commanderies of Lintun and Lelang the Eastern Division Commandant's Prefecture was set up.
〔In my view, the Account of Joseon has four, Zhenfan, Xuantu, Lintun, and Lelang, but here there is Pyeongna and no Zhenfan. It seems that these are two names for one land.〕
