What happened to the ending of the movie Chills?

In my personal opinion, the story takes place in the Hong Kong police station in Hong Kong. As the financial center of Asia, Hong Kong is known as the "safest city." Unexpectedly, the police station received an anonymous call and the other party Claimed to have hijacked a frontline assault vehicle of the police force, as well as five police officers and weapons and equipment in the vehicle. This incident attracted great attention from the top brass of the Hong Kong Police Force. It just so happened that the Commissioner of the Hong Kong Police Force (who is often referred to as "Brother 1" in Hong Kong movies, because the Commissioner's number is 1, hence the name) was not in Hong Kong at this time. At this time, Li Wenbin (played by Tony Leung Ka-fai), deputy director of the Eagle Operations, and Liu Jiehui (played by Aaron Kwok), the young deputy director of management, were in charge of this case, and the operation was named "Cold War", with Li Wenbin serving as the commander-in-chief.

"Chill 2" has aroused heated discussions among many viewers. Because the film has many story clues and complicated relationships between characters, many fans have some doubts about the plot and story. In response to the two major questions that have been discussed a lot, "Peng Yuyan was shot several times and survived" and "Man Yongshan fell to the ground and died", Tony Leung Ka Fai explained on behalf of the director that Peng Yuyan was shot by Aaron Kwok in the tunnel, and the bullet did not hit the head, heart and other vital parts. It passed through his body and did not cause absolutely fatal damage, just excessive blood loss. Wen Yongshan died due to severe injuries to her head and cervical spine after falling from a height.

Regarding "a major event that happened in 1995" in the film, Tony Leung introduced that the Political Department of the Hong Kong Police Force was disbanded in 1995, and the police force used the disbandment plan to send away some senior officials and police officers who had access to confidential information. Li Wenbin, played by him, used this plan to send away many of his old subordinates who had served as undercover agents.

Tony Leung Ka Fai also revealed that the scene in the film where Peng Yuyan gave him glasses was something he suggested to the director. He explained that this can strengthen the interaction between father and son, and also strengthen the process of Li Wenbin's role transformation. The two directors followed his advice, and the pair of glasses became an important prop in the movie: at first he wore a pair of rimmed glasses, and later changed to rimless glasses given to him by Peng Yuyan. When he officially "jumped" in court, he took off his glasses and wiped them slowly, symbolizing his transformation from being disciplined to having no scruples.
