After a while, she dangled her little feet and, finding it hard to hold back much longer, said, "Chengcheng, I'll tell you a joke."
"Mm, sure."
"Once upon a time, there were two rich men, A and B. One day, they were walking in a garden. As they walked, they suddenly found a pile of dog shit on the path. A said to B, 'If you eat this dog shit, I'll give you 50 million.' Deal. Then they found another pile, and B said to A, 'If you dare to eat it, I'll also give you 50 million.' A, who was feeling sore about the 50 million he just paid, ate it all up neatly. After a while, A and B embraced and cried their eyes out: they hadn't earned a penny, but each had eaten a pile of shit! Yet they added a billion to the country's GDP. Haha." She began to amuse herself, laughing with a cunning look.
"What's GDP?" Mo Liancheng asked.
"Gross Domestic Product."
"Is that another joke from your world?"
