Cao Fang replied: "It's a little strange, that is, although Luo Zhiqiang looks very sad, how can I feel that there are some acting elements in it, some of which are contrived, not like the expression of real emotions, but as if they are deliberately being done for us." ”

Xiao Wei smiled: "Yes, I feel it too." It stands to reason that this time is the time when Luo Zhiqiang should be the saddest, but you see, although he is in a state of mind now, his clothes are very neat and clean, which shows that this is a person who lives very carefully and pays attention to his own image, this is such a person who pays attention to the details of his image but smokes half an ashtray. ”

"Also, have you noticed, just now when I asked him if he often lives in the unit, he made a gesture of touching his neck, and his feet involuntarily crossed, which is to indicate nervousness and pressure. According to medical reports, there are many nerve endings below the chin and above the throat, and touching it can lower blood pressure, slow down the heartbeat, and calm the whole person. When a person is nervous or stressed, he will unexpectedly touch his neck to soothe himself. ”

"If a person is busy with work and often works overtime and is on duty, this is a very positive thing to live in the unit, why does Luo Zhiqiang feel nervous and stressed when I ask this question?"

"It means that he is nervous, we asked this question, but there should be nothing to be nervous about overtime itself, it should be people who are nervous. You say I'm right. Cao Fang said with a smile.

Xiao Wei continued: "You are very right, that's what you mean. So who is he going to stress about? Or who is going to stress him?"

"He Hongxing! There are basically only the two of them in this library now, so Luo Zhiqiang must be nervous about He Hongxing. Cao Fang said affirmatively.

"I didn't expect you to know this, but we didn't even learn these things in the police academy. Cao Fang looked at Xiao Wei with some appreciation.

Xiao Wei smiled embarrassedly and said: "It's not that I know a lot, it's just that I've been interested in this aspect since I was a child, so I naturally watch more." In fact, this is not unusual, and professional research has been carried out on this aspect during the Cold War in the West. ”

"When the KGB spies in the Soviet Union, this was a necessary interrogation method, which is what we called physiognomy in ancient times, also called physiognomy, which belongs to the category of the side door. However, it is also very scientific, but most of the charlatans at that time used it to cheat money, and they didn't use it in serious places. ”

Cao Fang nodded convincingly and said: "Although I haven't learned face observation in the police academy, but I have studied criminal psychology, just now I said that Luo Zhiqiang was nervous He Hongxing, it was based on his psychological judgment, I think the relationship between these two people is not as simple as the relationship between colleagues as they say." ”

Xiao Wei looked at Cao Fang with approving eyes and said: "You are all professionals, professionally trained, I am just a sideliner, I just know a little fur, little trick, I just hope to help the case." ”

At this time, he happened to walk to the edge of the school playground, Xiao Wei said: "I'm a little tired from walking, let's sit down and rest, and by the way, I will tell you my opinion." ”

Cao Fang nodded, sat down on the bench next to the playground, and listened to Xiao Wei.

Xiao Wei also sat down and said, "Look, this chair is a bench, and it is generally a space for three people to sit. But now the two of us naturally sat on one side of the chair. What does this mean? It shows that although we are familiar with each other, we are just ordinary friends and colleagues, so it is natural to keep a certain distance. ”

Cao Fang looked at where he was sitting and where Xiao Wei was sitting, and there was really a place vacant in the middle.

"You mean, He Hongxing came in and sat very close to Luo Zhiqiang just now, and there wasn't enough space?"

Xiao Wei nodded and continued: "Yes. At that time, there were two rows of sofas in the room, Luo Zhiqiang sat on one side, and we sat on the other side. This is normal, because from a work point of view, we are the inquirer, and Luo Zhiqiang is the inquirement, so the two of us sit on one side and Luo Zhiqiang sits on the other side. ”

However, when He Hongxing came in, Luo Zhiqiang asked her to sit down and talk. At that time, there was a single sofa next to the three-person couch where Luo Zhiqiang was sitting, and it was close to the door. Under normal circumstances, He Hongxing should sit on the single sofa, but how did He Hongxing actually do it?"

Cao Fang recalled and replied: "Yes, she didn't sit on the single sofa, but chose to sit on a three-person sofa with Luo Zhiqiang, but what does this mean? Maybe He Hongxing subconsciously felt that it was convenient to sit on the couch and talk to us, and I noticed that they also kept a certain distance, although it was not as far away as we are now, but it was not close to each other." ”

Xiao Wei said: "Officer Cao Fang, you did observe very carefully, it is true. ”

As he spoke, Xiao Wei suddenly said, "Who do you think is coming over there?"

Cao Fang turned his head to look at the other side, and said, "Who, who's coming?"

At this moment, Xiao Wei quietly moved his body closer to Cao Fang, a very close distance almost next to each other, but he had not yet touched Cao Fang's body.

When Cao Fang turned around, he was startled when he found that Xiao Wei suddenly appeared beside him, and immediately reflexively stood up and said, "Hey, Xiao Wei, what are you doing?"

Xiao Wei smiled: "You don't have to be nervous, I don't want to do anything, just test your reaction." ”

As he spoke, Xiao Wei retreated to his original position, pointed to Cao Fang's original position and said, "Cao Fang, you sit down and listen to me." ”

Cao Fang looked at Xiao Wei suspiciously, and sat down hesitantly, wanting to see what Xiao Wei continued to say.

Xiao Wei looked at Cao Fang and said, "Cao Fang, you must have been muttering in your heart just now, what is the matter with this Xiao Wei, why is he suddenly so close to me, what do you mean, and you may even wonder if this Xiao Wei has some intentions, right?"

Cao Fang smiled embarrassedly: "That's not true, it's just that you suddenly got so close, it's just that you have some conditioned reflexes and don't quite adapt to it." ”

Xiao Wei said: "Your reaction is the reaction of a normal person, and this is also a matter of distance. When a person arrives in an unfamiliar environment that does not belong to them, they will stand against the wall or sit on the side in order to find security. ”

"I've seen some foreign sources, which say that the American cultural anthropologist Edward Hall once said that there are four kinds of spatial distance between people, the first is the public distance, which can be as far as 360 centimeters;"

"The second is social distance, which is about 120cm to 360cm, as if we were talking to Luo Zhiqiang across a coffee table just now;

"The last is the intimate distance, from 45cm to zero distance, just like relatives, very familiar friends, couples and couples, will only appear in this situation; unless the relationship between two people is very close, otherwise a stranger invades your intimate distance, you will have a subconscious feeling of being violated, will unconsciously avoid, just like your reaction just now. ”
