Why do taxi drivers easily encounter dirty things at night?

Burning the midnight oil is something that some logistics truck drivers often do. Generally, when they are tired, they stop at the service area or the temporary stop on the roadside to rest. At night, the yin is very heavy, people who burn the midnight oil often stay up late, and watching the road in the dark for a long time will make people very tired. It is very easy to encounter some unclean things at this time. Burning the midnight oil is actually taboo, which is also related to Feng Shui.
