Generally speaking, the worst time of the day begins at five o'clock in the afternoon. At this time, the sun begins to set gradually, night begins to fall, and those ghosts hiding in the underworld begin to become active.
From 17 in the afternoon, the yin qi will gradually increase, reaching the peak at 0: 00 in the morning, and then gradually decreasing. At 4: 00 in the morning, the ghosts will slowly recede, because the sun is about to rise.
Although monsters are superstitious, if you go out alone, you should really pay attention to safety at night. Many people who kidnap, extort and rob halfway hang out at night, especially girls, don't go out alone in the middle of the night. These bad guys are like ghosts in the underworld, and their hearts are very dark, so be sure to pay attention.
