What is the prototype of the Quanzhou case in "The Burning Sun"?

The movie "Sunspot" is adapted from the novel "Sunspot". Because some real event elements were added to the movie, some viewers misunderstood that it was adapted from real events. Overall, the movie is fictional. .

In the novel, the three people are exactly criminals, and there is no so-called fourth person. The plot of the movie has been changed a lot. Due to editing problems in the later period, Chen Bijue’s character’s front and back images are somewhat incoherent. However, in the film He ends with a monologue that clarifies the truth to the audience. He has an IQ of 160 but has always presented himself as a fool, so he has been pretending to be stupid in order to reduce the possibility of being suspected.

Except for Chen Bijue, Xin Xiaofeng has been a co-police officer for so many years and has never thought about a salary increase or promotion. Yang Zidao has helped countless people as a taxi driver, but he has never given any interviews. There is a scene in the film where he was stabbed by a gangster. In order to prevent others from discovering his experience, he dragged his injured body to bandage alone. After watching this scene, I understood how much he wanted to continue living.

The ordinary lives of the three people were broken by the arrival of a policeman named Yi Guchun. It turned out that Yi Guchun had never given up the investigation of the reservoir murder case for so many years. Only after meeting Xiaofeng did he get some clues. . In order to eliminate the police's suspicion, Xiaofeng deliberately designed himself to become a homosexual in the eyes of Officer Yi. In the end, it was discovered that everyone was living in everyone's design, living in redemption and evasion of guilt.

When Xiaofeng and Yang Zidao were executed, the audience understood that the so-called murderer was only a temporary accomplice, and the real murderer was the fourth person. When they were executed, no one told the truth.
