It expresses that Cao Cao is like a dragon, leaping into the clouds and eyeing the world. The so-called worldview is nothing. How arrogant Cao Cao's wording is, "I can catch, not a hero, how can I be a hero?" Wait a minute. Liu Bei seems to be a hidden dragon. Because the time is not up yet, and the wings are not full, you have to rely on the strength of others to take a step back. In times of crisis, he can use his quick wits and overcome difficulties skillfully. He deserves to be the hero that Cao Cao refers to.
