Jiang Shu handed the playing cards to his Magic Assistant, Su Xiaoou, and then said, "Now that you have the playing cards in your hands, you can also pass on secret signals to me, right?"
"Mhm." Su Xiaoou nodded as she took the cards.
"I will tell an audience member picked at random to choose a card, flip it over, see what it is, and show it to everyone," Jiang Shu explained, "Of course, I will instruct him seriously to place the chosen card down carefully, so I can't tell anything from its appearance."
"Then you'll blindfold yourself and turn around while the audience picks a card?" Su Xiaoou understood; she could guess what would happen next, "This seems pretty simple."
"Yes, I won't be able to see during the reveal, but you will, so I can know the audience's chosen card by the way you hold the cards," Jiang Shu said with a smile, "Once I know the audience's choice, the rest of the performance is under my control, any speech will do."
