Sinkholes, sinkholes, everywhere. An unsuspecting young woman in Xi'an found herself suddenly swallowed up by a sidewalk which caved in as soon as she stepped onto it. Fortunately, a cab driver who was passing by witnessed the accident and came immediately to her rescue, as seen in the surveillance video above. However, it wasn't until firefighters arrived on the scene much later that the girl was pulled out to safety. In a similar accident earlier this month in Beijing, another young woman suffered 90% burns after falling into hot water from exploded pipes underground after the pavement beneath her suddenly caved in. She died soon afterwards in the hospital.
