How did Jackie get slapped?

Jackie was slapped in the face to promote the film. Because the theme of the film is boxing and Jacky is the protagonist, the performance of boxing duet is chosen as the "appetizer" of the play. Please go on stage to fight against a strong man, about the same age as Jacky, with short hair. He looks professional in blue sportswear. Although I don't know if he is a professional boxer, his momentum is very aggressive.

At first, the two men shook hands on the stage with a smile on their faces. It seems that they have a good relationship. But the next scene stunned the audience, only to see the strong man in black slap Jacky Cheung directly in the face. You can clearly hear the sound from the video, which shows that this is not a fake fight, but a real fight.

Jacky, who was slapped, was dumbfounded at first, but he didn't suddenly get excited. Instead, he smiled at the fans who slapped him. He explained to the audience: "It doesn't matter, it's all about the actors." Seeing this situation, Xiang Tai failed to stop it, but smiled from ear to ear.

Because the video exposure time is relatively short, everyone doesn't know the ins and outs of the matter, and everyone feels incredible. However, after many searches, some netizens found a very long video. In this video, the two men stepped forward, the strong man in black whispered a few words in Jacky's ear, and then guided Jacky to the designated position, and then what everyone saw happened.
