Another secret recipe of Master is very traditional, but it has also been skillfully used in the film, that is, "alienation effect". In order to illustrate the application of alienation effect in this film, let's talk about the outstanding style of director Wong Kar-wai. In Wong Kar-wai's urban movies, there are always a lot of soundtracks interspersed among them. In this regard, Zhang Yimou once said with great appreciation that when a melody rings somewhere in Wang's films, it will immediately arouse some emotions of the audience and create a full atmosphere. It can be said that in order to convey the unique emotional experience of the characters in the film to the audience, the soundtrack played a very good role in Wong Kar-wai. In "Let's Speak", the function played by the soundtrack can be said to be the opposite in many cases-creating alienation effect, repeatedly pulling the audience out of the immersion of the story, reminding the audience to keep critical observation of the characters in the film at all times, so as to better witness the formation, accumulation and outbreak of absurdity and let the audience laugh when their emotions are relatively detached from the story process.

In the scene where Zhao Xiaoshuai first went to a nightclub to catch up with Liu Delong, Xiao Shuai disappeared and rushed into the practice room and gym with a kitchen knife. Roaring music poured out of every room, so we heard many popular songs (all about love and affection) strung together, accompanied by the screams of the ladies and Zhao Xiaoshuai's kicking at the door. Zhao Xiaoshuai rushed in and out of the screen quite violently, a kind of. This passage clearly shows the intention of this film: while giving a comedy story, taking simplicity and folk customs as a reference, exposing the flashy elements in the current urban life, and completing the cultural criticism of urban life in the form of comedy. In the film, two whitewashed old ladies groaned and sang "Eighteen-year-old Brother", while Zhao Xiaoshuai and Northeast elder sister, who were about to commit crimes, sang "Eighteen Girls and Eleven Flowers", all of which reflected the director's intention in this respect.
