Chapter 20 secret

I heard two stories recently and found them very interesting, especially this one. When people ask too many questions in the future, I think I will tell him this joke.Frederick the Great of Germany was probably at war. A general came to see him and asked him what strategy he was using. "Can you keep a secret?" said the emperor. He swore to the sky and said: "I can be as silent as a grave, like a fish, like a fish in the deep sea." "I can too," said the emperor.
