Who knows this poker trick?

Feel free to take out 15 playing cards.

Let the audience remember one (by dictation)

Divide the cards of 15 into five parts, each with three cards, and then ask the audience which card he chose.

Will be placed in the middle of five copies (first take two copies in your hand, then put the one with the card selected by the audience on top of those two copies, and finally cover the other two copies)

Divide the cards into three parts, with five cards in each part (one card in each part, the first card in the first part, the second card in the second part, the third card in the third part, the fourth card in the first part and the fifth card in the second part ...)

Ask the audience which card he chose after playing.

One card chosen by the audience is A, the other two are B and C ... Put B in your hand, put the first card of A on top of B, the second card of A on top of the first card, the third card on top, the fourth card (about half below B) and the fifth card (about half above B), and finally put C on top (even with B).

Finally, push down first, then push up, so that the selected cards are finally pushed out.
