The eldest prince Cao Fu followed Sima Yi to participate in the Battle of Xiangyang last year, but the whole army was wiped out, and the eldest prince never came back. Not only did he not return, but he was never heard from.

Like Sima Yi, everyone knows that after he was captured, he took refuge in Shu and became a great official of Shu, but there were many Wei generals who were captured at that time, except for a few people who took refuge in Shu, many people have not been heard from since.

Cao Fu is one of those people who have no news, everyone doesn't know whether he died in battle, and they don't know if he defected to Shu Han, but fortunately, if Cao Pi knows that he has defected, I believe Cao Hong's life will be even more sad.

The people of Wei did not know that this was done by Shu Han on purpose, and this was to protect the families of those generals who were captured or surrendered. Needless to say, if the Wei court knew that those people had defected, then their families would definitely be affected, unless the whole family was rescued like Sima Yi, otherwise, their families would definitely be killed by Cao Pi.

Feudal society is sometimes more cruel than the underworld, and people in the rivers and lakes sometimes pay attention to "morality in the rivers and lakes", and it is said that the disaster does not affect the family, but in the feudal dynasty, if a person commits a crime, it will often harm the family, the same clan, and even the township, which is the system of the feudal dynasty.

In order to prevent those obedient generals from being "Yi Three Clans" or even "Nine Clans", Shu Han temporarily concealed the identities of these people and asked them to change their names and surnames to serve in various armies. The outside world only thought that they were missing, and Wei could not do anything to their families until they received accurate information about their whereabouts.

For those captives who still refused to submit, Shu Han also took the same measures to protect their families. Because, although they are still unwilling to submit to obedience, it does not mean that they will not be willing to submit in the future, as long as they do ideological work slowly, I believe that most people can still be transformed.

If their family members are killed for their own business, then they will be left with a mustard in their hearts, and the loyalty of these people will be affected to a greater or lesser extent. If they can find a way to save their families now, they will be grateful to Shu Han in the future, and without worries, they will serve Shu Han wholeheartedly.

Cao Fu belongs to the kind of person who refused to submit at first, he is one of the core personnel of the Cao family, both his personal and family interests are closely related to the Wei court, plus he is also relatively upright, he can be said to be loyal to Cao Wei, and belongs to the most difficult type of person to transform.

However, the political commissars (who joined the army) in the Hong army are not vegetarians, they have insight into people's hearts, and they are the best at doing ideological work, and they have thousands of means to make the iron man turn into a finger twister.

These people can be said to be the first group of people to study psychology, and they have even set up psychology courses and research institutes in the college to study and study these problems. At present, the problem of transforming captives is the hottest research topic in the School of Psychology.

After all, the Hong army has won successive battles and captured a huge number of captives, providing them with a large amount of research materials that can be used for them to conduct massive research. Over the years, they have also made a lot of research results, and created a set of systematic methods for transforming captives, which can be summed up in four words: "teaching students according to their aptitude".

The allusion to the idiom "Teaching Students According to Their Aptitude" comes from the Analects of Confucius, which tells the story of Confucius giving different answers to different students on the same question. Because each person's congenital conditions, acquired environment and education are different, each person has their own unique personality and values.

Personality and values have a direct impact on how well people perceive and accept certain things. Therefore, these psychological researchers must first classify and divide people's various personalities, but also classify and divide various value orientations, then study the psychological reactions of different types of people to different things, and finally study how to change the value orientation of these people

These questions are complex and not so easy to study, but fortunately, people in this world have not yet experienced the big bang of knowledge, and people have little experience, little education, and little knowledge, and correspondingly, their thinking is far less complex than that of later generations.

During the Three Kingdoms period, there were only a few types of human personalities, and there were very few types of value orientations, and most of them were loyal to the monarch, which brought convenience to the research work.

In layman's terms, most people in this world have fewer eyes and simpler minds. Of course, it can only be said that most of them, but there are also a small number of people who have many eyes and complex minds that can be passed down through the ages, and these people are the so-called wise men, or strategists.

The representative figures are Zhuge Liang, Sima Yi, Pang Tong, Lu Xun, Jia Xu, Xu You, Xun You, Guo Jia, Chen Gong, etc., in no particular order, and some are not listed, the stories of these people's wisdom are passed down through the ages, which shows that their wisdom can also occupy a place in history.

Okay, let's not talk about it so complicated, let's get back to the problem of Cao Fu, Cao Fu has a more upright personality, is not greedy for money and beauty, is very loyal to Cao Wei, and is brave and not afraid of death. The method of coercion and inducement against this kind of person will not work, and the means of sending money, beautiful women, and official positions will not only have no effect on a person of his character, but may also have the opposite effect.

Cao Cao just didn't understand psychology back then, and sent these things to Guan Gong, wanting to buy Guan Gong with these material things, but Guan Gong was a "righteous man", very righteous, and disdained these material things at all, so Cao Cao was never able to subdue Guan Gong's heart, and finally Guan Gong still hung the seal and left, and then passed five levels and cut six generals, and rode thousands of miles to find his brother Liu Bei.

Cao Fu's situation is a bit similar to Guan Gong, but it is not exactly the same, after all, everyone is an independent individual, everyone is unique in this world, and there can be no identical individual. However, although they are not identical, they have a lot in common.

For example, they are more "righteous", in fashionable terms, they are more sunny and have more positive personalities.

To deal with this kind of people, we can use a similar method, that is, to use "great righteousness" to influence them, arouse the kind of compassion and compassion in their hearts, so that they know who is the true ruler of the country and the people, and who chooses to assist the people to get the world, so that the country can truly become strong, the world will be peaceful, and the people can live and work in peace and contentment.

For a key figure like Cao Fu, the transformation department attaches great importance to it, and they even hired a professor from the Institute of Psychology to tailor a set of "learning courses" for him to brainwash him for more than a year. Of course, in addition to political needs, this matter is also a good research topic.

It is not a simple matter to transform the core figure of the enemy, if it can be done, it will be a great achievement both politically and academically, and its significance please refer to my dang's probation work on the last emperor Puyi.
