Come out and hang out, you have to pay it back sooner or later. Tell me about it.

"If you fool around, you'll have to pay it back sooner or later." Several people in Infernal Affairs said.

First of all, at the beginning of the movie, Ceng Zhiwei seems to say something similar to his brother, but this is definitely not the original words.

Later, Tony Leung Chiu Wai said:

Then Wu Zhenyu, the new boss of Infernal Affairs 2, told others what his father had said.

This sentence can be said to be classic.

Everyone is a slave to this sentence, and there are many ways to get out of it, so there are many ways to return. It's strange that whoever comes out to hang out will have to pay it back sooner or later.

Maybe someone else will give it back to you, or maybe you will give it back to others. In short, this is the price of hanging out.

Maybe more people can't understand why they have to pay it back, because more people are mixed up. Tit for tat, of course.

That's why I hang out. Actually, it's very simple, because I want to return it.

What goes around comes around!
