One day, Ali Baba was caught by robbers, and the robbers asked him for the incantation to open the gate of the cave. But at this time, Alibaba faces a dilemma. If the password is told to the robbers, it will have no use value and will be killed in the end. If you don’t tell the robber the mantra, the robber thinks he doesn’t know the mantra, and he will still be killed.
How can you make them believe that they do know the spell, but not what it is.

He suggested to the bandit leader, “you are 30 meters away from me, and then point your bow and arrow at me. When you raise your hands, I will recite a mantra to open the cave gate; when you put your hands down, I will recite a mantra to close the cave gate. If I run away, you will shoot me with bows and arrows.

The robber raised his right hand and saw Ali Baba’s mouth move a few times. If the stone gate really opened, the robber raised his left hand. After Ali Baba’s mouth moved a few times, the stone gate was closed again. The robbers still don’t believe it. It’s not a coincidence. They keep changing the rhythm and raise their right hand and left hand. The stone gate opens and closes according to their rhythm. Finally, the robbers think that if they still think it’s just a coincidence, they are a fool, so they still believe Alibaba.
