What did Qizhi Hao Yong tell us?

We should be a thoughtful and effective person, and don't blindly pursue courage or make meaningless blind worship, otherwise we will make jokes, even get hurt seriously, and the consequences will be unimaginable.

Or:

In order to compete for the reputation of "bravery", two reckless men actually cut off each other's meat to eat, until finally, because of excessive bleeding, both of them died. When they hurt each other, they actually misunderstood the meaning of courage.

What is "brave"? Courage is not superficial recklessness, but a rational belief. There are different levels of courage. No matter what the result is, it is useless to act on impulse. And truly brave people, in order to get a suitable result, will do things that ordinary people dare not do. If you misunderstand the true meaning of courage and act rashly, it will cause many meaningless behaviors, including wasting your life.
