Surveillance video captured a scary scene in northwest China Saturday, when an unspecified ceiling decoration collapsed onto a people-packed escalator. The incident occurred at the Huashan Mountain tourist center in Huayin City, and Fox News reports at least nine people were injured, though none seriously, per news.com.au. The footage shows those on the escalator look up a split second before the material came crashing down. The cause of the collapse is under investigation. Huashan Mountain is a destination with religious significance, having been home to a number of prominent Taoist monasteries. (This remains one of the worst escalator stories we've covered.)
