There is a saying among Chinese people that many schools were built on the site of old mass graves in order to use the righteousness of young people to suppress those evil things. But after all, it is a place full of evil and filth, and strange things will always happen in special times. For example, on cloudy days or in July when the ghost gate opens, the yin energy is strong, which breaks the original balance of yin and yang. At this time, some strange things will happen... Therefore, many schools have more or less true or false legends, and some shocking cases have occurred.
And I am a swindler who makes a living by cheating, and I have never believed in supernatural ghosts and gods. But after experiencing so many strange things, I can only say, "You can't believe it, but you can't be disrespectful."
