The Eastern Secret Passage is 67 meters long with 84 steps, deliberately designed to be winding to avoid pursuers and direct gunfire. In addition to reinforced concrete, the uneven walls enhance sound absorption, making it difficult for pursuers to locate even if they are behind. The passage is equipped with 43 explosion-proof lights, so in the event of an explosion, fragments will not cause secondary harm.
