1. Correct me. Wenfeng's phrase "Why did you betray me" was not addressed to Kuang Zhili, but to Andy On. Later, he said, "Michael, why did you betray me?" The man who betrayed Wenfeng was Andy On. In addition, both Wen Feng and Lin Jiadong are subordinates of Li Wenbin, and Wen Feng is a former police officer who found ND 157 in Aarif Lee. At that time, Li Wenbin was in charge of O-Records (Organized Crime and Triad Bureau), and Wenfeng was an update with South African nationality. They realized that Li Wenbin's hawkish line may no longer be taken seriously and will always be at a disadvantage, so they began to take action. After careful organization and Li Jiajun's assistance, the two thumbs disappeared, and the Mong Kok bomb incident happened. However, after learning that someone was going to kill him, he took the initiative to contact Lin Jiadong, the only person he trusted, to find out who was going to kill them (this story participated in the dialogue between Li Wenbin and Aarif Lee, the Independent Commission Against Corruption).

2. The original boss of the film was neither Li Wenbin nor Liu Jiehui. At the end of the film, Li Jiajun tells his father that people even his father can't imagine have been helping them. This can be called a mysterious organization for the time being.

3. The official didn't give a specific statement about whether Kuang Zhili was a traitor, but the traitor's suspicion is very great. Vincent, also known as Qian Jiale, is not the mole. He didn't betray Liu Jiehui, but Liu Jiehui is also a mortal. At the time of the incident, he once doubted Qian Jiale. Vincent's gambling plot arrangement is just a use point. Although he owes a lot of money, some people will not betray their brothers no matter how hard it is. Besides, the director of the Ministry of Finance is very suspicious, because he is forbidden to speak. There is a saying in the movie: "They began to clean up their homes. They would rather kill outsiders who helped them than betray their brothers."

4. The last book that Eddie Peng Yuyan Yuyang read in his cell was Shadow Warrior. The author is a member of the Australian SAS Special Forces. He was dismissed because of the austerity policy of the Australian government. He travels around with his pension. He met a group of militants in a small country in Asia. Sympathizing with their chivalry, he sneaked back to China, successfully robbed several banks with his professional training, and funded these guerrillas to buy arms. Shadow fighters are in line with Eddie Peng Yuyan's ideas in the play, so he didn't forget to enrich himself in the detention center and read his biography.

After the conversation between Liu Jiehui and Andy Lau, the shredded (non-shredded) document is a copy of Li Wenbin's character review report, which is invisible to Liu Jiehui.

The film received rave reviews on the Internet, misleading the audience. Most of the above are taken from the official reply and made some personal supplements.
