Ya Qiaoxi led Sun Hang and the other two on foot through a narrow alley, then passed right through a nearly completely collapsed stadium—between the ruins, there were many passages propped up by steel bars and beams. It was clear these passages weren't naturally formed during the collapse but were excavated by people in the aftermath.
The passages showed obvious signs of reinforcement; steel beams of vastly different ages were pieced together, and although the welding was unsightly, it was sturdy enough. Some cracks in the ground were covered with thick steel plates, while others were filled with cement. A hundred-yuan bill was stuck in a cracked brick seam; when Sun Hang pulled it out, he found it was a small advertisement card with a banknote pattern printed on the back.
