What is the principle of asking spirits? Please do me a favor.

Through the description of Dr. Zhang, the reporter learned that "asking the immortals" is a divination game. There are generally two people playing "Ask the spirits", and the tools are a pen with fluent handwriting and a piece of white paper (it is said that the bigger the white paper, the more effective it is). Immortals will write "1, 2, 3, 4, 5, 6, 7, 8, 9, 10" and "Tang, Song, Yuan, Ming, Qing and Jin" on both sides of white paper, and write "male and female" and "yes and no" on the other side. Write three alternative answers to the question in the box and circle them with words. To see if it works, usually one of them is a known correct answer. After the paper is laid flat, cross your hands and fingers and write with a pen. According to the rules of the game, elbow or wrist support is not allowed, so it needs to be suspended, and the pen is perpendicular to any point on the paper, ready to start. Immortals repeatedly chanting "past lives, past lives, I am your life, if you want to continue with me, please draw a circle on the paper." After a long time, the pen began to move magically, and the questioner began to ask questions, such as "Can I go to college?" "How many times have I been in love in my life?" The pen will circle in one direction. When the question is repeated, the pen will gradually move closer to the answer direction until it reaches one of them. After getting the answer, you need to say the mantra respectfully and send away the "ask the spirits". In addition to "Pen Fairy", there are similar games such as "Vegetable Fairy", "Chopsticks Fairy" and "Money Fairy". The reporter learned on some divination websites that "disc fairy" should be more particular. It is best to choose a quiet place, usually around 1 1 p.m. Props are a small white plate and a piece of paper. "They usually light white candles in the middle of the night to turn pens or plates and ask if they can achieve anything." Guo Zhengyi, a researcher at China Institute of Popular Science, told reporters about the "disc fairy" he witnessed. Professor Guo said: "Cai Xian pays more attention to laying a piece of cloth, drawing a pattern of" Yin and Yang fish "on the cloth, surrounded by words, and generally writing words related to fate, such as" wealth ","poverty "and" health ". Fasten the small dish on the pattern of yin and yang fish and draw a small arrow at the bottom of the dish. Two or three people stood around the table with their fingers on the bottom of the plate. Everyone is thinking,' Little Disc Fairy, come quickly'. Fairy seekers believe that when the dish "automatically" leaves the pattern of yin and yang fish and moves to other places, it means that the "small dish fairy" has come. No matter what you ask, the small arrow will move to a pre-written corresponding word, and the fairy seeker thinks that' disc fairy' is' effective'. " Similarly, after asking all the questions, you have to say a spell to send the disc fairy away, and the plate will return to its original position. Fairy hunters believe that if the dish fails to return to its original position, it means that the intention is not enough. "Fairy seekers believe that as long as" Pen Fairy "and" Disc Fairy "are effective for the first time, they can appear almost every time. So many people are fascinated by games. Especially on campus, students who worship this point should ask "ask the spirits to make a prediction" whenever they encounter any problems. The reporter followed up with some young people, who admitted that they had all played this game, some in middle schools and some in universities. Some of them ask about the future, some ask about marriage, and some predict good or bad luck. They told reporters that "ask the spirits to ask the spirits" not only needs sincerity, but also needs atmosphere. The silence in the middle of the night, the faint candlelight, the pious expectation and the high concentration of spirit constitute the best environment for asking "Ask the spirits". Some seemingly mysterious phenomena have puzzled many young people who are not deeply involved in the world. They firmly believe that it is "providence" that pens and disks can move by themselves. However, the expert's explanation uncovered this absurd scam.
