Wu Zhengguo asked, puzzled: "The overpass has safety hazards? What kind of hazards could there be?"
Wu Hua explained: "Dad, the overpass at Tongjiang Station is one-way with a narrow passage. If incoming and passing passengers get mixed together, a large crowd could easily cause a crush or trampling incident. We need to prevent this kind of hazard in advance."
Understanding the point, Wu Zhengguo laughed and said: "Xiaohua, don't you worry. What you're worried about won't happen. The passenger management at Tongjiang Station is very strict. They already have contingency plans for this, adjusting ticket-checking times according to train arrival and departure times to prevent congestion."
