Hello, I am very happy to answer your question

The experiment the author did to prove this famous saying is: The author did some breeding when he was a child. In the sparrow experiment, he put the captured sparrows in a cage and put the grains and bugs that the sparrows loved most. But the sparrows didn't even pay attention, they just stared at you with a pair of unyielding eyes. In the cage Zhong desperately rushed out.
