China's AAAAA-rated glass bridge cracks after teen pokes it with umbrella

China's glass bridge in Henan province, an AAAAA-rated tourist site, was evacuated after a teenager cracked one of its upper glass panels by poking his umbrella several times. An official clarified that the structure's overall strength and weight-bearing ability hadn't been compromised. The bridge, suspended about 180 metres above the ground, is designed to handle thousands of kilograms of weight.
