Can you tell me a joke in Degang Guo that I know the truth? thank you

Degang Guo: My former partner studied with the master at the age of 10. One day, the master said, "I'll teach you a word. Everyone you talk about is afraid of you." The apprentice was so happy that he quickly asked the master what it was. The master said, "I know the truth, and everyone who tells me is afraid of you."

The apprentice came home to see his father and squinted at him and said, "Hum, I know the truth." Hearing this, the father quickly pulled his son aside, gave him 50 yuan and said, "Don't tell anyone!" " "My son was overjoyed and soon saw his mother. He squinted at her and said, "Well, I know the truth." Mother was even more anxious. She quickly took out 100 yuan from her pocket and gave it to her son, saying, "Don't talk nonsense! "

My son was even happier when he saw it. As soon as he went out and met his uncle who delivered the letter, he wanted to try again.

He also squinted at the uncle who delivered the letter and said, "Hum, I know the truth."

The uncle who delivered the letter was very excited. Seeing no one around, he bent down and said, "Son, you finally know, let dad hug you ~ ~ ~ ~ ~"
