At 9pm 67-year-old Li Zhu’e was hobbling up the stairs to her 13th-floor flat after using the public toilet in her compound’s yard. Since the stairwell has no lighting, she held an electric torch in her right hand illuminating the steps as she climbed.

Li suffered a serious car accident in 2019. After two surgeries, a large piece of flesh was removed from her right leg, and she still has 12 metal pins in her lower back, limiting her ability to walk.
