In the dorm at night, everyone is getting ready to sleep.
   Liu said: “It’s too early to go to bed anyway. Why don’t you come to guess the riddle. I found that some idioms can be made into brain teasers to guess. It’s funny.”
   Xiao Zhang and Xiao Zhou hurriedly said yes, only Xiao Wang yawned and said, “Go to bed early. We will have class tomorrow.”
   Big Liu glanced at Xiao Wang and said, “Why are you going to bed so early? Would you like to have fun? Let me talk about it first. Guess what cloth is afraid of and what paper is afraid of?”
   Xiao Zhang, Xiao Wang, Xiao Zhou thought about it, but didn’t come up with it, Liu said, “I’m not afraid of ten thousand, but just in case, I can’t guess that simple.”
   After listening to Xiao Zhang, he smiled and said, “So I also think of one, which number is the laziest and which is the most diligent.”
   Liu said after hearing it, “It’s so simple, don’t do it, and don’t stop it.”
   Xiao Zhou gave a thumbs up and said: “Awesome, I also have someone who doesn’t know whether to guess or not. Xiao Bai looks like his brother.”
   Liu thought for a while and said, “This is difficult, but I guessed it, right?”
   Xiao Zhou and Xiao Zhang said: “Da Liu is great, and Xiao Wang, you can say one too.”
   Xiao Wang yawned and said, “Stop talking, go to sleep.”
   Liu: “No, I have to say it, and it has to be difficult.”
   Xiao Wang: “That’s OK, I really thought of one, but after guessing, I must turn off the lights and sleep.”
   Liu said: “Say quickly, I will turn off the lights when I finish talking.”
   Xiao Wang: “Three eunuchs are chatting.”
   Liu thought for a while and said, “I guessed it is nonsense.”
   Xiao Wang: “Yes, this also reflects the content of our conversation.”
   Liu Yi was awkwardly turned off the light.
