After watching it, I told my daughter-in-law that this film mainly reflects the complexity of human nature, or the complexity of human nature.

Almost all the characters in it are full of complexity. The story is not tortuous. A group of robbers robbed a jewelry store. The salesgirl was paralyzed because she had to call the police. A young man selling meat happened to be in the shop with his mother. His mother died of a heart attack. There was also a police informant among the robbers. Because the salesgirl was exposed, she was killed on the spot by the robbery gang.

The paralyzed salesgirl, her boyfriend, who was also the security guard of the jewelry store at that time, and the young man selling meat, the contact of the murdered informant, Ye Kechang, came together because of such an emergency and took revenge in private.

Brother Yuan, played by Wang Xinyuan, is the boss of the underworld and belongs to the role that younger brothers look up to. When they robbed, they were surrounded by police. He stood up and said, I'd rather be alone, so I rushed out and risked being shot dead by random guns.

Later, one of their gangs was killed and the stolen jewels disappeared. He knew there was revenge, but he didn't run away. He said that two lives can't be counted like this, and we must find out the real murderer.

In the process of looking for the murderer, he had many opportunities to kill the policeman who was chasing him. However, he didn't do that. He didn't want to kill innocent people, but he always let the police go. A brother of this gang was killed, and he happened to be there. Although he knew that a violent explosion would attract the police, he saw his brother's daughter-in-law being crushed under the cupboard, but he still tried to save people first and then evacuate.

A younger brother was caught and betrayed him, but he still said to his younger brother, I will distract the police and you run. Such loyalty is really commendable and has always been reflected in him. I don't just want to escape by myself. Seeing that Brother Yuan was trapped, he stepped forward and created an opportunity for Brother Yuan to escape.

Brother Yuan rented in a group rental house, and the landlord was an out-and-out ordinary citizen, greedy for money and mercenary. The landlord is a lady with eye problems, waiting in line at the hospital to donate corneas. Brother Yuan knew that he would die at any time in the process of tracing the real murderer, so he made a corneal donation in advance. After his death, his cornea was transplanted to the landlady, which made her see again.

Officer Ye is also very interesting. His public identity is the chief of police, and he should enforce the law impartially. But because the informant he contacted was killed by a robbery gang, it was actually a private revenge. If those robbers are caught by the police, most of them will not be sentenced to death, which is unacceptable to him. So he clearly knew where the robbers were hiding, but he didn't catch them by police. Instead, he asked the boy selling meat and the boyfriend of the salesgirl to come forward and directly kill the robbers.

He later found out that they had swallowed the jewels after killing the robbers, so he went to argue with them and asked them why they swallowed the jewels. When those people offered to give him a share, he only said that he could give a share to his informant. Such a plot always expresses the complexity of human nature.

"Know what is as important as going to work on time? Get off work on time! " This is another important figure in the film, that is, Lin policeman. When he was young, he worked hard, but he never got the chance of promotion and salary increase, and there was inevitably resentment in his heart. However, in the face of murder, he talked about getting off work, but he worked hard. He faced the moment of death many times and still didn't give up. Finally, he found out the truth and caught the murderer.

In real life, everyone is not a simple blank sheet of paper, and there will be no such simple gender as black and white. Everyone has two sides, many sides. It is with such a life foundation that the complex human nature reflected in the film will look more real and have a taste of life.

This is probably the greatest charm of the film.
