Why is the female ghost in red the most powerful spectre in folklore?

Although everyone believes in science now, and no one is superstitious enough to believe in ghosts, there have been many legends about ghosts among the people. The female ghost in red is the fiercest existence in folk superstition, and many horror movies will have similar images. Why is the ghost in red the best? In fact, this is more of an exaggerated superstition. It is said that the existence of the ghost in red is related to a folklore.

In superstition, it is believed that the ghost in red is the most ferocious, and most of them are the embodiment of people who have died unjustly. Now there are many stories about the ghost in red, which are fabricated by later generations, but there is a saying in folklore that Nu Wa Niangniang wears red clothes. Those who die unjustly will be blessed and sheltered by Nu Wa Empress after death, and they can wear red clothes symbolizing nobility. And because these ghosts have grievances when they die, they will find someone to vent and retaliate after they become ghosts, which is probably one of the reasons why the red wardrobe is so fierce.

In fact, ghost stories are superstitious, but in China's folklore, there are some well-known underworld figures, such as Yan Luowang, black and white impermanence, cow's head and horse's face, and so on. They are in charge of the underworld, mainly responsible for things after death.

According to folklore, Meng Po stayed at Naihe Bridge beside Sansheng River, and used to be mainly responsible for delivering Meng Po soup to ghosts. If the dead want to be reincarnated and live, they have to drink Meng Po Tang. Only by drinking Meng Po Tang Can can we forget the past. Some people don't drink Meng Po Tang. It is said that they will have a heavy experience of forgetting Sichuan. After a lot of pain, it is possible to reincarnate with the memories of past lives. People also believe that reincarnated people will leave marks on some parts of their bodies. I wonder if it's true.
