How did Peng Deming do his magic?

Let me explain it to you! Don't know right

At first, Peng invited Yao Ming to go to the stage to check the props, but the box, which was also a prop, was not shown to anyone, so I decided that there was someone inside. Then Peng Jin went into the box, and it was not Peng himself who reached out, but the one in the box. At this time, Peng has designed a box to reach the background. After the box was tied, it was hung. Finally, we saw that the box was scattered and there was a dead corner in the top cover. It is estimated that the man in the box is hiding there.

If you have any questions, please discuss them.
