General Li Guang? Wise, I advise you not to have the slightest. At that time, the Nanshan Tiger seems to be Shi Lei. What does this mean?

It's a poem about Li Guang. General Li Guang had a plan, but Emperor Wu never listened to his advice. After Li Guang was robbed of his position as a general, he went home to hunt in Nanshan. He seemed to see a tiger while hunting. When he drew the bow, he shot it. As a result, he found that it was a big stone and the arrow went deep into it. Li Guang was horrified by his divine power. But the bow can't shoot into the stone again. Li Guang sighed. Only when I meet the real enemy can I inspire my divine power.
