How does Wang Chong divide the tricks of fortune telling?

One day, Wang Chong passed by the street and saw the crowd, so he squeezed in. I saw a Taoist sitting cross-legged. In front of him was a golden Buddha with the words "Tathagata fortune telling" written on yellow silk. There is a saying in that population: "Everyone knows good or bad, and the Buddha knows it like the back of his hand. To say the reason, the Buddha made it clear that it was good or bad. The auspicious Buddha nodded, but the evil Buddha did not move. "

Wang Chong took part in accidental amusement and asked, "I want to do business. I don't know if I can make money? " I saw the old man bowed deeply to the Buddha, slightly opened his eyes and subconsciously kissed his lips. Then he picked up the golden ruler and circled the Buddha several times. The Buddha nodded frequently at once, and the old man put his hands together and said, "Congratulations, you will be rich in the future!" " He also asked Wang Chong for three taels of silver.

The next day, Wang Chong came to the street with a golden clay sculpture. He pretended to smile at the old man and said, "Please try this Tathagata." The old man was so anxious that he couldn't say a word. He hurriedly picked up the little golden Buddha and ran away. In this way, Wang Chong broke the Taoist priest's deceptive organ in front of everyone. It turns out that the Buddha statue is made of iron and its head can move. One end of the gold ruler is iron and the other end is a magnet. If the Taoist priest asks the Buddha to nod, he will hold one end of the iron bar and let one end of the magnet revolve around the Buddha's head. There is no reason not to nod, otherwise he won't move.
