Staff at Jinjiang Park station on Shanghai’s subway Line One clean water leaking from the roof, Jan 25, 2016, which had begun letting in water at about 6 pm, probably as a result of the city’s low temperature. Several doors were closed and passing trains were not affected. Shanghai’s temperature on Sunday, with a low of minus 7.2 degrees Celsius, was a record low for 35 years.
