Don't talk, know your last name.

Knowing your last name without talking is actually a numbers game. Here are some routines.

Divide one to one hundred into ten groups, for example, write one to ten, the second to eleven to twenty, and so on, and you can write ten. Note that the number of each card cannot be repeated. Then draw a big cardboard into ten squares and write ten numbers in each square.

But it is different from the number arrangement of cards, such as writing ten to nineteen in the first box, twenty to twenty-nine in the second box, and so on, and then filling one to one hundred in the ten boxes. Please note that the numbers cannot be repeated. In addition, I would like to remind you that there are more than one hundred surnames, except for some particularly unusual surnames, there are about four or five hundred more common surnames.

Whether it's a hundred surnames, 400, 500, or even 1000, you can use this method to guess. The only difference is that the more surnames are arranged, the more and more complicated they need to recite.

The process of knowing your last name without talking.

You can often see some fortune-telling booths in the street night market, you can know the surname of the bearer, and you can know the good or bad luck of the bearer. This is just a psychological calculation. There will be a note in your last name, writing down your life's fate. Of course, this note of fate may not be accurate. Tell the truth, but he can know what your last name is without saying a word.

First of all, the fortune teller will give you a deck of cards full of surnames and ask you to find a card with your surnames on it. Then on a piece of cardboard with several squares, many surnames are written on each square. Let you find the box with your last name on it. Cover the card with your surname on the box with your surname on it. In this way, the psychic will know your last name by counting his fingers.
