毕岚 / Bi Lan (late Han)
毕岚 / Bi Lan enters the wiki through Hanji 936 as the palace official who casts bronze figures, bells, a Tianlu beast, a water-spitting toad, and mechanical water devices for 汉灵帝.
The episode’s point is not that mechanical ingenuity is itself illegitimate. Bi Lan’s devices matter because they appear beside imperial hoarding, new palace construction, rebellion, frontier pressure, and hungry people, turning technical spectacle into evidence for 时绌举赢.
