The first part of "Infernal Affairs".

This movie does not rely solely on the appearance of heroes like other Hong Kong police and gangster films. Instead, it impresses the audience with its exquisite plot, chic and neat camera editing, and uses ups and downs of the plot to express the conflicts between the characters.

In addition, this film shows the complex relationship between police and gangsters, but it is not limited to the intrigues between each other. Especially the tragic death of Chen Yongren in the end makes "Infernal Affairs" break out of the general police and gangster film, where justice will eventually defeat evil.

The director's good intentions are also reflected in the application of many other film techniques. For example, the film frequently replays the scene where Liu Jianming watches Chen Yongren leave the police academy, using the misplaced starting point of their lives to promote the development of the story.
