What does the joke about father and son riding donkeys show?

If you blindly listen to other people's comments, you will lose your judgment, and finally you will be at a loss and accomplish nothing, just like this father and son. Therefore, you should learn to make up your own mind, think, judge and decide with your own brain, and once you have made a decision, you should stick to it firmly and don't care too much about other people's opinions, especially those irresponsible and nonsense. Learning to use our own brains and forming the habit of making up our own minds is an important aspect of cultivating our self-reliance and self-care ability.
