"That was over a decade ago. Speaking of which, it has something to do with Red Pig."
Niu Ma, holding the wine Liu Zheng offered, started telling the story.
"Oh? How so?"
Liu Zheng played along.
"Back then, wasn't it trying to sneak across the border? Although I didn't agree with the idea, I still helped it scout out whenever I had the chance."
Niu Ma said cryptically.
Scouting naturally meant finding less vigilant spots of the Border Control Bureau.
"One time, when I was scouting, I noticed a guy acting all sneaky, so I discreetly followed him."
It continued.
"Boss, how can you call someone else sneaky?"
Liu Zheng squinted and said.
"Mind your own business, kid. Do you want to hear the story or not?"
Niu Ma glared.
"I want to hear it, please go on."
He quickly responded.
"If you want to hear it, then keep quiet. Interrupt again and I'll shove this bottle in your mouth."
Niu Ma threatened while shaking the wine bottle in its hand.
Liu Zheng mimed zipping his lips.
