The Dongmi Trail spans 67 meters and includes 84 steps, designed with deliberate twists and turns to avoid pursuers and stray bullets. Additionally, the uneven surfaces of the walls, aside from being reinforced with concrete, enhance sound absorption, making it difficult for pursuers to pinpoint locations. The tunnel is equipped with 43 explosion-proof lamps, ensuring that in the event of an explosion, debris will not cause secondary injuries.
