What are the intriguing details or eggs in Detective Chinatown 2?

At the railway station, Qin Feng was shocked when he saw the murderer take out the scalpel. There is no blood on the scalpel. If he just killed someone, there should be blood on the scalpel. However, this does not mean that the deceased was just in a coma, but that Yi Song stayed behind to call the police while chasing the murderer. The next day, the police came to the scene and vomited, indicating that the body died miserably. However, if it is an autopsy, the body should be relatively complete and clean, and the police are used to autopsy ... Can it be inferred that the doctor was an accomplice and the third person was killed by Song?

Xiao Yang's hot eyes entered the doctor's office, and he found that his wife's photo, ballpoint pen and computer orientation were all on the left, even the mouse was on the left, and it was a left-handed mouse. When the doctor first appeared, he teased police officer Chen that he would not throw up next time and still use his left hand.

So as long as you pay more attention at the beginning, the murderer is easy to find. I don't know if it's an egg. The Tang people left underwear and high heels on the right side of the bed, suggesting that the doctor slept on the left. In addition, at the beginning of the film, it is said that the deceased was cut in a Y shape, and there are three common anatomical forms. Y-type, T-type and Y-type are the most common in American movies. If the organ can be removed by this method, it can be preliminarily inferred that the murderer has certain medical experience. This is why half of the doctors are skeptical. Sean's younger sister's name, after proving that Q has something to do with this matter, it is easy to link money with Q, and the suspicion comes out. At the beginning of the airport, there seems to be a man in black with his back to Liu Haoran in the camera.

Finally, the police came, and the light hit Liu Haoran's face, half bright and half dark, perhaps symbolizing justice and evil? It's a bit like echoing the harmony of yin and yang of Taoism, and finally echoing the first one. Liu Haoran said that his dream is to complete a perfect crime. He didn't find the killers hidden in these two films. Maybe it means that Qin Feng is not an absolute justice person. He is satisfied as long as he knows the truth and doesn't want to bring everyone to justice. He is looking forward to blackening himself into a perfect crime. what do you think?
