In the movie Infernal Affairs 2, this is Ni Kun's dictation before his death. The original Cantonese words in the play are "Come out, no matter what you have done, you must return it in advance", which is what gangsters love to say. Now it has become one of the popular expressions on the Internet, and the most popular one is Sima Yi's sentence "Come out and get mixed up sooner or later".

I hope I can help you. Good luck.
