The next night, Dr. Liu continued to explain to me the details of the tracking technique.

"Gao Yue, today I will talk about the necessary qualities of tracking personnel, which mainly include three aspects: physical quality, mental quality and psychological quality. Specifically, there are the following points: First, it is necessary to have an ordinary appearance. A stalker will attract attention if their appearance is too prominent, so a good stalker should not have any physical characteristics that can attract the attention of others! The second is to have the mental ability to attract attention. Trackers should always pay attention to adapt to the environment in which tracking is implemented, and have the ability to integrate with the tracking environment, such as looking like local people or staff, etc.; The third is to have the staying power of the body. Gao Yue ...... I don't think you need to say much about this, you can understand! Tracking often takes a lot of time and long, tedious waits, and if you can't even keep up with your stamina, then don't do it! Fourth, it is necessary to have good eyesight and hearing. The core of tracking is to observe with the naked eye! Therefore, good eyesight is the foundation, keen hearing can hear the clues of certain sounds, and various sounds can often play an important role in the investigation! Fifth, it is necessary to have the ability to be resourceful. In the process of tracking, many unexpected situations may be encountered, and the tracker must have the resourcefulness to use various strategies and methods to deal with unexpected events; There is also a need to have a good memory, and there may be no opportunity to record the situation for a long time during the tracking process, so the ability to recall and remember is very important! I think you must master these qualities and requirements! Especially after going out, we often have to track Qin Lingjin's whereabouts, and these requirements are essential! Physician Liu said.

"I got it, I remembered it all!" I replied aloud.

"There are some other qualities, such as the ability to disguise, the ability to rely on yourself, etc., which you can slowly explore and experience in practice in the future...... Now let's talk about hiking tracking, which can generally be divided into single-person tracking, two-person tracking, and three-person tracking (triangular tip). Generally speaking, high-quality trekking tracking should have multiple participants to ensure that there are no accidents in the tracking, but due to manpower limitations, we often track by one or two people, and the following will focus on these two tracking skills. ”

"The first is the one-man approach: where there is only one follower, the investigator should rely on strategy and, above all, experience and talent. Trackers need to maintain tight control over the subject without revealing themselves. In outdoor situations, when there are crowds or large number of people, the tracking person should shorten the distance with the object, and conversely, when there are fewer people, the distance from the object should be extended...... You can often see this in spy movies, right? ”

"Yes! There are a lot of such shots in spy movies...... Following behind others is very particular about distance! I replied aloud.

"Right...... In the case of surveillance, the position of the tracking personnel should be kept within a distance sufficient to see the object clearly, so that the purpose of monitoring is best achieved, so that effective measures can be taken decisively at any time according to the activities of the subject. Investigators are to approach or close to the subject when approaching or about to turn into the complex to avoid detachment, and if necessary, to follow the subject from across the road to avoid being spotted. When the subject walks into a shopping mall with several entrances or exits, the tracker should also approach the building, follow the subject as much as possible with the flow of people, and adjust the distance to the subject according to the location of the subject. Sometimes, when a subject enters an office building or other separate building, the tracker should determine if they can follow him, and sometimes they can choose a suitable location outside to wait for him until the subject appears, and then continue to track! Of course, there are many other occasions and scenarios, and the specific methods are different, which requires a lot of experience and summary...... I won't go into detail here. ”

"Okay...... I know. I said out loud.

"One last word...... Let's expose countermeasures after a tracking attempt. Gao Yue, it's very common to be discovered by a target as an investigator! In fact, it will follow, which does not show the quality of the investigator's industry! If an investigator is found by the target and is able to deal with it appropriately, he or she can get out safely or continue to follow after treatment...... That's amazing! Based on previous experiences and lessons, there are a few ways I can teach you! If you're driving, you'll have to realize in the shortest possible time that you've been discovered by your target! You must act immediately, or you may be misled! In this case, we can speed up and overtake the target, giving him the illusion that we are not following him but following him...... Got it? ”

"I understand that."

"There is also the possibility that you can continue to follow the partner car, and if you don't have a partner car, you can change the car and continue to follow according to the local conditions. And walking, generally in close proximity, be sure to hide when the other party wants to turn back but doesn't see you, only a few seconds, if he sees you, don't hide anymore, you can turn around and go into another place, or approach him, look at him at a glance to understand his expression, analyze whether it is suspicion or curiosity! Then think about whether to continue, and if there is danger, then retreat immediately! Oh yes...... When stalking, don't stare at the other person, just look at his waist, because if you don't make eye contact, he won't remember you! Unless your clothes are particularly bright, if you don't have the special training I said before, how many people can remember how many people look like when you go to the mall? ”

"Also, if the suspicion is discovered, don't behave abnormally, if you continue to walk naturally and generously, it will not arouse suspicion." Dr. Liu exclaimed.

"Doctor, in fact, while you are talking, I am imagining in my mind the scene where we are following Qin Lingjin together...... If we could actually get out, how exciting it would be! I'm going to have to take my chances...... Get out there early! I shouted.

"Soon......" Dr. Liu replied.

We stopped for dry food.

……

"Physician...... Actually, I'd like to continue hearing it today...... What about your love stories...... The story of you and that salon girl......" I asked suddenly.

"Don't talk about me, tell me about you...... Oh yes, Han Bing seems to really like you...... Do you have feelings for her? Physician Liu asked with a smile.

"Han Bing? I feel like she's a little tempted by me...... That time at the hot spring resort, I could feel it...... Later, she drove over to find me, and we chatted at the western restaurant just to deliver clothes to me...... Very nice feeling! I recalled.

"Han Bing is beautiful...... It's simply unbeatable...... I don't think there's a man who doesn't like such a woman! You were pretty good at the time! Dr. Liu laughed.

"Nor did ...... I also have a good impression of her, but I am a family person, so I can't love her...... That day, we were in the forest park, walking along the paths under those towering trees, and I could clearly feel the surging in her heart...... She is an angelic girl, beautiful and beautiful...... I'm a little tempted, but I can't delay people's ......" I closed my eyes, and Han Bing's charming and moving appearance appeared in my mind.

"It's a pity...... She's already become the woman who gave birth to Qin Lingjin......" Dr. Liu said loudly.

"yes, that's a pity...... Qin Lingjin, this scumbag, is really a big victory......" I gritted my teeth angrily.
