How did the yellow bird draw lots at the temple fair? Can you believe it?

Call you a biological training method. The breeder can deal with the bird's hunger and then put the rice grains on the bamboo stick. (Note that the rice grains are white. When a bird is hungry, it will naturally make white rice grains. After a period of training, birds peck at white spots. (Of course, the breeder may not feed white rice. In this way, the lottery effect of the yellow bird will come out. I suggest you search for a famous experiment, Pavlov conditioned reflex experiment. There was once an essay by Jiang Kun called Leadership Colon, in which I also saw conditioned reflex, which was very interesting. Of course, I can't draw a correct conclusion about the accuracy of the lottery according to my personal preference.
