I explained it in high-sounding and easy-to-understand words: I used to be a dragon, but today I swam to the shallows and was teased by shrimp. I used to be a tiger, but I couldn't play in Pingyang and was bullied by dogs. One day, when I turn over, I must do something earth-shattering
To put it simply, a capable person encounters difficulties or reaches the bottom of his life. At this time, he was bullied by incompetent people, and he encouraged himself to regain his glory one day.
