The sensor lights in the stairwell are very dim. If you have poor eyesight, you can only grope your way in the dark while walking in the stairwell!
For those who frequently use the stairwell, this situation is beyond their control to change. After all, this old building is in an old neighborhood without any property management. Even the sensor lights installed at each floor's entrance are connected to individual households' wiring. Some elderly residents have chosen not to install sensor lights at their doors to save a bit on electricity bills.
When An Yin reached the third floor, she encountered this problem: the stairwell was pitch black. Luckily, she turned on her phone's flashlight.
After descending, she walked along the uneven road towards Mrs. An's bookstore.
There was a section of the road without streetlights. An Yin held up her phone, lighting up the road, and watched the ground carefully, not noticing an elderly person walking towards her.
