右北平 / Youbeiping Commandery

右北平 / Youbeiping Commandery enters through Hanji 972 as the home commandery associated with 田筹. The episode introduces Tian Chou as a young local talent from this frontier setting before 刘虞 sends him toward the court.

In this source, Youbeiping is mainly a background node for frontier credibility. Tian Chou’s later movement through 居庸关 and his retreat from 无终县 into 徐无山 make his authority local and border-facing rather than only court-derived.
