"What is 'cats and dogs going ashore'?" Du Jiaojiao came over with a puzzled face and asked.
Zhao Yu said: "Cats and dogs going ashore is an idiom!"
Du Jiaojiao furrowed her brows, "How come I've never heard of this idiom before, second brother, have you heard of it?"
Grandpa Du shook his head.
"None of you have heard of 'cats and dogs going ashore'? I thought I was the only uncultured one; turns out, you are even less cultured than me!" Finding two people even less knowledgeable than herself, Zhao Yu laughed smugly.
Let's see who dares call her dumb now!
"What 'cats and dogs going ashore'!" Ni Yang came over and smacked Zhao Yu's head, "It's called 'assuming an air of decency!'"
Du Jiaojiao burst into laughter, "Hahaha! So it's 'assuming an air of decency'!"
