The case reasoning of the Spring Festival movie "Detective Chinatown 2" is quite interesting, and the setting of the case in the case is even more unexpected, the whole process is both hilarious and brain-burning, and it is amazing by this detective series of movies.

In Detective Chinatown 2, there's an app featuring top detectives from around the globe. The app has a detective ranking, the second is Qin Feng, the third is Noda Hao from Japan, and the first is the mysterious q.
The character setting of q is the most brilliant place in "Detective Chinatown 2", and "who is he" has always been a big suspense in the film. Until the end, who q is still not revealed, today may wish to analyze q.
The following contains spoilers and is only for fans who have already watched it to study together.
q The murderer of a serial killer? When the movie story is in the middle, it creates such suspense. Later, after the murderer appeared, it was clearly revealed that Q was not the murderer.
At the end, Qin Feng burned his brain to analyze and deduced that Song Yi was q, and this reasoning was the biggest reversal of the movie, and it was also the most amazing place.
According to Qin Feng's logic, the reason why Song Yi appeared in the first two murders was not that he was instructed by Q, but that he was obsessed with murder.
After checking the materials in the library, he conducted a comprehensive analysis of the case, concluded that the murderer would continue to kill, and deduced the next place of the murderer's murder, so he set up a bureau to take Qin Feng to the park to "meet the murderer by chance".
When the murderer killed the fourth person, Song Yi arrived first, dropped the body, and replaced the Lu Guofu he killed with the "fourth victim", but in fact, the victim was someone else, hidden in Song Yi's rear compartment, and later people unconsciously disposed of it.
All this reasoning makes sense. However, when they were separated at the airport, the hacker master's second-dimensional sister told Qin Feng that q's IP was not in Canada or in the United States, and Song Yi had a perfect alibi, and overturned Song Yi's reasoning that Q was q.
Which Song Yi is not q? If not, who is it? The serial murder case of "Detective Chinatown 2" is considered to be closed, but who q is has become the biggest suspense point, causing heated discussion.
Could it be that Q is Song Yi's sister? Estimates are unlikely.
Could it be that Q is police officer Chen Ying? The brain hole is a little too big, and the possibility is actually not very large.
Wouldn't it be a beard? emmmmm
Which q is who the hell is that? In fact, from this movie alone, Xiaobian still thinks that Song Yi is q, and Qin Feng's reasoning is correct.
Camouflaging IP is not difficult for Q, and from the perspective of Q's style of acting, Q will definitely disguise IP, which is more in line with Q's character setting, and the reason why Qin Feng is surprised is that Q's mind is meticulous.
Looking at it again, Song Yi is the proof of Q. Remember Song Yi's last expression after listening to Qin Feng's analysis? From being cute to deep, it also said: When you stare into the abyss, the abyss is also staring at you. It's okay to look, but don't look too long. This is certainly not Song Yi's line, but q's.
After that, there is also a picture of Song Yi processing the chalk. Song Yi was left-handed, just like the murderer, so when Qin Feng observed him, he began to use his right hand, this ability to adapt to changes, if Song Yi was just a Song Yi, he estimated that he could not do it with a general IQ.
There is also Song Yi who took Qin Feng to the park to "meet the murderer by chance" in order to first clear his suspicions of committing crimes, first protect himself and then push behind his back. And the best disguise of q is great wisdom and foolishness, and the reason why Qin Feng let go of q is because he firmly believes that Song Yi is q, and he sees through but does not say it thoroughly.
Of course, it is not excluded that q did not really appear in "Detective Chinatown 2", but someone else, which is another biggest possibility.
After all, the open-ended ending is more charming, Chen Sicheng's skills are indeed not ordinary, he can make a big fuss in "Detective Chinatown 3", introducing a new role to interpret q, which is also reasonable to explain that q instructed Song Yi to carry out the perfect crime according to his ideas.
However, on the whole, Xiaobian still thinks that Song Yi is q, what do you think?
