Among this group of people, the person with the most pressure is not Qin Tai, but Qin Tai's wife Zhan Xiaoxiao. Because Zhan Xiaoxiao is going to play a person she has never seen before, she is Zhang Yue. It is not the first time that Zhan Xiaoxiao has played someone else, nor is it the first time to pretend to be a lady or lady of the official family, but Zhan Xiaoxiao is always a little nervous. is not because of the prestige of Zhang Yue'e's mother's British father-in-law, nor because of the prominence of Zhang Yue'e's mother-in-law's Xu family in the capital, let alone because of the crime of pretending to be an official, but because Zhan Xiaoxiao knows too little about Zhang Yue'e, and she is worried that she will not be able to play Zhang Yue'e.

As early as when Qin Tai and his party were handling cases in various places, they needed to play various characters as cover. Because they generally handle cases independently, they have not informed the local yamen in advance, and it is even more impossible for the yamen to help them investigate the case with great fanfare. Therefore, it is necessary to secretly investigate and handle cases without alarming people, which requires secrecy and makeup. At the beginning, because of the word "makeup", Qin Tai, Zhan Xiaoxiao and Xiao Lingzi were not criticized by the old drunkard master. The old drunkard master did not rely on the old to sell the old, nor did he deliberately find an opportunity to criticize Qin Tai and others, but sincerely wanted to do good for everyone and worry about everyone's safety.

"We are not a play, and we will not be a play. The general drama plays who is like whom, otherwise it will not be recognized by the audience below. Therefore, they must at least be similar, and good actors will be even more godlike, so that they can become household names. We don't need applause and praise from others, and we don't need everyone to remember us. Because we don't do it for food, it's just a means to solve a case. It's a big deal to start over again, it's really not good, it's a big deal not to act, change an industry. We can't do this, because if we use this as a cover, once someone sees through it, the small ones will not do well, and the big ones will be exposed or even lose their lives. So not only is we not a play, but we have to act more realistically than a play. The old man summed up a sentence, I hope you will understand and understand. The drama is playing a person, so it needs to be like the best god. We're not acting or acting, so we don't need that. Mentally remind yourself that I'm not playing this person, but that I am this person. ”

This is the original words taught by the old drunkard master, and it is also the dogma that everyone often reminds themselves of when using their identities to cover up. Later, it also became Qin Tai and Zhan Xiaoxiao's famous words when they taught Qiu Xiaoqiu, and gradually became Qiu Xiaoqiu's motto when handling cases.

According to today's terms, the method of using a fake identity to cover up their investigation and handling cases is called disguise investigation, but at that time, ordinary yamen would not do this. Except for a very small number of people in the Criminal Department and people from the secret agency, ordinary people don't know and won't think of this kind of disguised investigation. But this kind of disguised reconnaissance has brought a lot of benefits to Qin Tai and them, not only to facilitate the investigation, but also to make them more like ordinary people. In this way, it is not only closer to the people, but also more integrated with the people. Later, Qin Tai simply gave up the general way of handling cases, and often used civilian clothes to travel, when there was a case, it was considered a disguise investigation, and when there was no case, it was a private visit to Weifu.

Gradually, they have experience, and often explore their experiences according to their own conditions, and correct or study each other. The old drunkard master also told everyone his experience and understanding without reservation and provided it to everyone for reference. Soon after, Qin Tai and the others almost all became experts in this area, to say the least, they were veterans in this area. They summarize the most important contents, record them as their own experience, and can also teach their future students or assistants. Nowadays, the "Three Principles of Plainclothes" summarized by Qin Tai and his wife have become relatively complete teaching materials. It's a pity that there is only one student who really learns, and he is Qin Tai's cousin Qiu Xiaoqiu.

The so-called "three principles of plainclothes", when organized according to the current language, are the three major elements and taboos of disguise investigation. First, people-oriented, not conformist. This means that according to the case, geography, and the needs of the situation at the time, the character, occupation, age, gender, etc., can be determined. It is not permissible to determine which person a certain person must play, and it is not possible to arbitrarily disguise yourself as a certain person to go out to investigate without analysis. For example, if a case is investigated in a private market, the investigator must not appear disguised as an official or a soldier. Because this is not only too conspicuous, but also easy to attract attention, and even reveal your true identity immediately. If you want to disguise yourself as a detective in the bazaar, it is better to play the role of a vendor or a subordinate of a large family, which is not only inconspicuous but also does not attract the attention of others. Taking the five people of Qin Tai as an example, the best investigator should be Zhan Xiaoxiao or Xiao Lingzi, and if it really doesn't work, Ma Sandao can also do it. The old drunkard master and Qin Tai are not suitable, except for the last resort, it is generally not recommended to use these two people to disguise themselves in the bazaar for reconnaissance.

Second, don't play roles that are too different from yourself. Although the fake identity is fake, it also needs to have a little relationship with yourself, otherwise it will be counterproductive if it is exposed. The old drunkard master has reminded everyone many times that even if you want to disguise yourself for investigation, you need to choose a good cover identity according to your own characteristics. For example, Ma Sandao's look, playing a bodyguard or thug, almost without any makeup. If Ma Sandao is asked to use the identity of a butcher or a meat seller as a cover to investigate the case, it is no problem, because Ma Sandao used to be a pig killer and meat seller, which does not require much understanding or adaptation to acting in his true colors. But if you want a person like Ma Sandao to play a playboy or a reader, it will make people feel strange, even if Ma Sandao himself is not exposed, it will make people suspicious. The purpose of using a fake identity as a cover is to approach or follow the other person without attracting everyone's attention. Once the identity is exposed or the fake identity attracts everyone's attention, the role of disguise detection will be lost, which is equivalent to the failure of disguise investigation. At that time, Zhan Xiaoxiao was a little unwilling to admit defeat, saying that she could play anyone, and she could adapt to it immediately if she was a fake person. The old drunkard's words immediately made Zhan Xiaoxiao speechless and expressed his convincing at the same time. In the folk market, it is common to see drunk people who are drunk and bare-chested. Can Zhan Xiaoxiao play this kind of drunk well? The answer is yes, Zhan Xiaoxiao can't play this kind of person. First, Zhan Xiaoxiao doesn't know how to drink, and he doesn't have this kind of experience and experience of getting drunk; Second, Zhan Xiaoxiao has never been drunk, so he doesn't know the posture and inner changes of walking after being drunk, so Zhan Xiaoxiao can't act. Even if she insists on acting, Zhan Xiaoxiao can only be a god at most, and she can't achieve the highest level of being a drunk; Third, Zhan Xiaoxiao is a girl, even if she and Qin Tai become a married woman, it is impossible for Zhan Xiaoxiao to really get drunk and walk on the street with her chest and stomach exposed. So Zhan Xiaoxiao is not like a drunk. This is the point put forward by the old drunkard master, don't try to play a role that is too different from yourself as your own cover. The fake identities suitable for the old drunkard master include a down-and-out scholar, a failed businessman, a poor teacher, a poor fortune teller, etc., which is not suitable for playing a rich man or a street vendor. Ma Sandao is suitable for playing the thugs or traders of large families, especially those who kill pigs and sell meat, and are not suitable for playing scholars and officials. Qin Tai's true character is to play a scholar or a gentleman, and he can play a small boss or a businessman, etc., and is not suitable for playing gamblers, hooligans, prostitutes, and corrupt officials. Zhan Xiaoxiao is suitable for playing playboys, prostitutes, scholars, chivalrous, heroines, tooth women, etc., and is not suitable for playing the five big and three rough laborers, market vendors or rude soldiers. Xiao Lingzi is suitable for playing the role of Xiao Er, buddy, follower, errand runner, hawker, herald, soldier, Yamen's officer, etc., and is not suitable for playing officials, officers, bosses, and gentlemen. The reason is that Xiao Lingzi has foreign blood, and the imperial court does not allow this kind of person to be an official, and Xiao Lingzi does not look like a boss with a successful career at this age.

The third, and most crucial, is not to play the role of someone you don't know. The old drunkard repeatedly reminded everyone that if you want to disguise yourself to investigate, you must do your homework in advance, otherwise you will fail. This homework is not only to cover the identity itself, but also to adapt to the local geography and customs. To play as a local, you need to be able to speak the local dialect, otherwise you will show your feet. Playing an outsider requires you to say a few words from time to time that are suitable for this person, whether others can understand it or not, you need to cover your true identity in this way. If you are playing the role of a vendor, you need to be able to use dictatorship, and know the local prices and market conditions. If a vendor doesn't know what he has in his hands and doesn't know the local market, the vendor will attract attention and reveal his identity. So when deciding who to play, you need to be thoroughly aware of the various influences that come with that person's identity. Generally, Qin Tai will find some inconspicuous cover identities, and will not specifically designate a certain person as a cover. But if necessary, they will try to collect all the information about this person and try to play this person as well as possible.
