How to perform magic numbers overnight?

This kind of magic is also called "Zhuge Shenshu", "Kongming Shushu" and "Counting before the lamp". This is a fortune-telling method. Use a life book, put it in a paper bag, and write down your last name, first name, year, month and date of birth in advance. Please tell people their names, ages, parents, wives and brothers. Performers can calculate accurately. This is not a real skill, it belongs to the method of passing the door by hand. Making this magic public can break superstition. The following "iron wonder" and "silent god" can all be similar tricks.

Description:

Make four bags out of thick paper, about one inch eight minutes wide and two inches five minutes long. On the surface of the bag, the words "Taoist magic" are written, and the style is as shown in the figure (four bags make a style). In three of the bags, there are a batch of letters of life (the names are scrawled). A small door is opened in the middle of one bag, and the words such as name, age, name, parents, brothers, wife, etc. are left in the letter of life, and then folded, so that the above paragraphs can be gathered in one place. In addition, dozens of small bills (about three inches wide and four inches long) are used to make a stack. A small ticket is pre-written with a hexagram, a hexagram, tens of thousands, hundreds of dozens of numbers. Put it on a small table with a colored bag and hide it in a book (turn the receipt upside down). When using, take any one of the three bags, let others hold it in their hands, and then ask their names, ages, etc. (One by one on the blackboard), then take out the small tickets in the book (when you take them out, the reverse side is open, so there is no word, and the number head and the color bag are invisible), turn them quickly in your hand (make the color bag number head in front), and write the number with a pen as an excuse. In fact, this person's name, age and other words are written in the small door of the color package (finished. Plug and bag day). After writing, put the color package under the receipt (the color package was originally on the receipt, but now it is inserted under the receipt, so you can see the numbers on the receipt and the color package is hidden below). Then, pull the receipt with the number and put the bag on it with someone else's hand (excuse to check, right). Turn the receipt over in the blink of an eye.
