Since Zhao Dun's term as Zhongjunjiang, the post's jurisdiction was widened and its holder automatically obtains the regency of Jin.
Approaching the end of its existence, Jin was troubled by the civil wars waged by its own retainers against each other.
[7] According to Chunqiu Dashibiao (春秋大事表) by Qing dynasty historian Gu Donggao, Zhongjunjiang is etymologically the origin of the Chinese words 將軍 and 元帥.
The word 將軍 (Jiāngjūn, Shōgun, Changgun, Tướng quân, "General") derived from Zhongjunjiang.
Another alternative name 元帥 (Yuánshuài, Gensui, Wansu, Nguyên soái) is used in the four countries as a translation and equivalent of the English word "Marshal".
