This movie is very classic. In my opinion, there are two reasons for its success. Externally, it is an excellent police and gangster film, with gunfights, chases, and brotherhood. The relationship is presented directly to the audience. The character played by Liu is a very smart person. He later defected and killed Zeng. Because of his "success, all the bones will be withered." Liu's role is like a wolf in sheep's clothing. Because of his undercover identity, his external and internal identities are the exact opposite, and he is the "righteous" villain. Liang is also undercover, but he is more righteous. Maybe he is also confused. After too many years, he is still undercover. No matter how white the lotus is, he is afraid of being contaminated by mud, so he complained to Huang, when Huang took out his watch and told him that he was too fast. On his birthday, this tough guy was moved. In the past few years, his former lover had a six-year-old child. His emotional life was empty and his nerves were tense, so Huang became the only person who believed in him and the only caring person. He hated such a person dying in front of him, but he was helpless. A friend in the gang died, and he was still covered before his death. All these made Liang hate the spies in the police even more. In the end, Liu's identity was revealed in front of his girlfriend, and he went higher and higher. Killing Zeng he seems to have Opportunity to make a choice, so he said "I didn't have a choice in the past, now I just want to be a good person", which also explained his revenge for Liang by shooting his partner. This film creates another possibility for police and gangster films. This kind of identity exchange intensifies the contradiction. It is interesting and delicate, love, loyalty, back... In the end, no matter who it is, it is not a body. Involuntarily?
