"Then the winning side can give the losing side a small punishment, how about that?"
Qin Yu did not doubt it, and she had always been very confident in her intelligence, so she nodded directly: "Okay, no problem, you go ahead!"
Zhang Jingdong pretended to think for a moment, then said, "First question, motionless for half a day, suddenly moves, the top is happy, the bottom-- is very painful, name an activity."
Qin Yu immediately frowned, deep in thought.
Although she had never heard this riddle before, she felt that Zhang Jingdong's riddle seemed... a bit risqué.
After a while, she vaguely thought of an answer but hesitated to say it.
Luckily, just now Zhang Jingdong said that she must guess only one to win, so she hesitated for half a minute, then shook her head: "This... I can't guess, you tell me, what activity?"
"Fishing."
Qin Yu instantly understood, her face flushing with embarrassment.
