One day, Zhuang Gong, King of the State of Qi, went out in a chariot to hunt.
On the way, he saw a small insect raise both its arms, trying to stop the wheels of the chariot. Zhuang Gong of Qi was curious and asked the driver: "What kind of insect is it?"
"It is a mantis," the driver replied promptly. "This kind of insect only knows how to advance but not retreat, blindly underrating its enemies and overrating its own abilities."
Hearing the driver's reply, Zhuang Gong smiled to himself and remained silent.
