First of all, the Taiyuan Wang clan issued dozens of recalls to him, ordering him to return to Taiyuan immediately and not to stay in Chang'an, and at the same time forbidding him to propagate his doctrine.

Originally, Wang An came to Chang'an because of the ban in the clan, but he didn't expect the family to still not forgive, and he wanted to ruin the situation that he had managed so hard. At that time, Wang An was still too young, and he had been the pride of the clan since he was a child, so he never thought about what the family would do to him.

However, Wang An did not think at all that the doctrine he preached had hit the foundation of Confucianism, and as a scholar class derived from Confucianism, he would not allow this doctrine to have room for survival at all, and as the representative of the scholar class, the five surnames and seven hopes were naturally the vanguard of eliminating this heresy.

Because of this, the Taiyuan Wang family saw that the recall of Wang An had no effect, and decisively punished him, first let the clan interrupt Wang An's supply, Chang'an is not easy to live, he can't survive without money, and then let Wang An's father, that is, Wang Guo's grandfather, personally order him to come back, the so-called father's life is undeniable, no matter how stubborn he is, but he does not dare to disobey his father's order, plus he is penniless, so he has to return to Taiyuan obediently.

However, as soon as Wang An returned, his personal freedom was immediately restricted and he was locked up at home and not allowed to go out. His father was also an important figure in the clan, and he was very sad for his intelligent but deviant son, and he hated him very much for the doctrine of rejuvenating the country through industry and commerce, and strictly implemented the orders of the clan, not allowing Wang An to have any chance to go out.

Wang An, who couldn't go out, was still not discouraged, his time in Chang'an opened his eyes, combined with the practical experience he summed up when he was an official, plus some things from his own thinking. It gave him the idea of writing a book and a speech. I just have time now, so I can calm down and start a new pen.

It was in this mentality of being at ease with what happened that Wang An began to write a book that affected his life. And it took nearly ten years to write this one, and the draft alone was stored in two large rooms, after the book was completed. Wang An named this great work on the relationship between industry and commerce and the state, society, and individuals as "On Industry and Commerce".

After completing the theory of industry and commerce, Wang An was drunk for three days, and then secretly found someone to prepare a book to print, and secretly gave it to some friends in Chang'an, wanting to spread it through them. Because he had been hiding in the house and writing books for the past ten years, the Taiyuan Wang's surveillance of him was also relaxed a lot, which made Wang An's early plan very successful, and the industrial and commercial treatise was quickly printed into a book and sent to Chang'an smoothly.

Just when Wang An thought it was done. The Taiyuan Wang clan finally discovered this book signed by Wang An and circulated in secret, and the high-level of the lower clan was finally furious. Not only mobilized the power of the entire Wang family. He also contacted several other companies with the surname of Wuwang and Qiwang, and worked together to collect all the industrial and commercial theories that had been circulated. Then, in front of Wang An, not only all the books were burned, but even the manuscripts he had worked hard for ten years were burned.

Seeing that all the hard work in the first half of his life was in vain, and it was his father's own hand, which made Wang An unacceptable for a while, and under the anger in his heart, the whole person became crazy, blocking the door of the Wang clan ancestral hall every day, starting from Emperor Xuanyuan to scold, until Wang Yun, who pushed the Wang family to the world's famous family, and then from Wang Yun to the current Wang clan, the Wang clan who was in power at that time was scolded one by one, and even his father was scolded. His talent is a good learner, although he is crazy, but he still does not scold people.

The Wang clan saw that Wang An was mad, and they didn't want to worry too much about a madman, but Wang An scolded too fiercely, and even the ancestors scolded together, they really couldn't afford to lose that person, and finally unanimously decided to expel Wang An from the family, and Wang Guo's grandfather was also disappointed in his son, and then broke off the father-son relationship with him, and even made the decision, so that Wang Guo, who was already a teenager at the time, also broke off the father-son relationship with Wang An, and from then on he only had a grandson, no son!

In this way, the crazy Wang An was driven out of the house alone, but after all, Wang Guo's grandfather still had some true feelings for his son, so he began to make some arrangements for Wang An's life, not only gave him a set of yards, but also took food and clothing from the family, and even sent servants to take care of him, and there were doctors to help him diagnose and treat him every few days.

But because of the blow of his son's incident, Wang Guo's grandfather's health deteriorated day by day, and he died in less than a year, and the power of the family fell and was seized by Wang Guo's second uncle, that is, Wang An's younger brother. At first, the younger brother showed a bit of generosity, and took care of the eldest brother who became a madman according to the rules set by his father, but later after he had a firm grasp of the power in the family, he slowly cut off Wang An's use and let Wang An fend for himself.

Without food and clothing, coupled with madness, Wang An slowly and really became a homeless madman, and because of his special background, the whole Taiyuan City knew that there was such a madman, and many boring people saw that the Wang family really didn't care about Wang An, and began to treat him as the object of ridicule, usually wantonly ridiculed and insulted, as for Wang An's former relatives and friends, they also hid one by one, deliberately forgetting the prince of Wang An, who was in the wind in the jade tree.

However, Wang An's bad luck did not end like this, as his son, Wang Guo was also implicated, when Wang Guo's grandfather was still there, naturally no one dared to do anything to Wang Guo, but with the second uncle at home, he naturally looked down on him, the eldest grandson of the long house, and deliberately attacked and excluded everywhere.

Fortunately, Wang Kuang inherited his father's intelligence, and under the blow of the second uncle, he slowly learned to forbear, even if he knew that his father was bullied and abused outside, he didn't dare to look at him, for fear of being caught, and when the brothers in the clan scolded him for being the son of a madman, he didn't open his mouth to defend himself, but just studied hard, and wanted to take a fame before sending his father out of Taiyuan.

But it backfired, no matter how careful he was, but he was still remembered by people with a heart, when he was less than 20 years old when he was admitted to the middle school, he was told by the clan that he wanted to give up the imperial examination and take charge of the business in the clan instead, and the reason was that his father advocated industry and commerce, so he, as a son, naturally did not need to enter the imperial examination, and the management of business in the clan was regarded as a son inheriting his father's business.

Faced with such an arrogant decision in the clan, Wang Guo was extremely angry and hateful in his heart! But he is not Wang An, many years of life under the fence, so that he has an unimaginable forbearance, and finally smiled and took over the task assigned to him by the clan, and studied hard, slowly made a lot of business, and regained a certain position in the family.

Maybe it was God who had mercy on Wang An's father and son, just when Wang Guo walked out of his life path step by step, Wang An's madness slowly improved, although life was still down, but his sanity finally returned to normal, but for the people in Taiyuan City, Wang An's impression of a madman has been deeply rooted in his heart, and no one regards him as a normal person at all.

From crazy to a sane normal person, Wang An recalled what happened to him over the years, plus he was originally a learned and astute person, and suddenly had a sense of enlightenment, almost all the conditions in the world have been seen clearly, and nothing can blind his eyes, and it was at this time that he got acquainted with the old man Dürr, and he was very bored to point them a few times, just like a game.

After Wang Guo slowly had some say in the clan, he wanted to take care of his father Wang An, but there were still many people in the clan who did not like him, so he didn't dare to do it too obviously, but he secretly met Wang An a few times and sent a lot of money and property, but Wang An did not appreciate his son's kindness at all, and threw out all the property sent by Wang Guo, and at first he didn't even want to see Wang Guo's face, and even said that their father-son relationship had been broken, so don't do these senseless things again.

Wang Guo began to think that his father was angry with the Wang family, so he refused to see him, but later he learned through another very important person that his father Wang An was afraid of affecting him again, so he didn't dare to show too close to his son. After knowing this reason, Wang Guo felt even more guilty in his heart, as a son of man, his father suffered outside, but he couldn't do anything, what could be more uncomfortable than this kind of thing?

And Wang An seemed to know that his doing this would make his son's heart even more uncomfortable, so he wrote out a point of view in his theory of industry and commerce, and then secretly passed these things to Wang Guo through a person, and told him that if he wanted to be a filial son, then learn all these things and pass them on, which was the best reward for his father.

At first, Wang Guo only began to learn these things because this was his father's life's work, but with the deepening of his contact with business theory, coupled with some experience of his own business, he immediately realized how powerful and broad his father's knowledge was, and then he was more attentive to study, and then he met Cui Yu, the two hit it off at first sight, and couldn't help but teach him what his father taught, and with the deepening of the friendship between the two, coupled with the relationship between an important person, Cui Yu also knew the existence of Wang An, And he also came to Taiyuan to ask for advice a few times, and Wang An seemed to be different from others to him, and patiently taught him many questions, so although he and Wang An did not have the name of master and apprentice, they had the reality of master and apprentice.

After understanding the intricate relationship between Wang An and Wang Kuang, the father and son, Li Su looked at Wang Kuang's eyes, and also had a little more sympathy and admiration, to be able to get ahead in that kind of adversity, and become an important figure in the Taiyuan Wang family, it seems that his vision was indeed right, this Wang Kuang is indeed a rare talent.

Of course, his father Wang An is a rare wise man, but it is a pity that he is too young to read the book on business and business, otherwise he would have to get a copy to read anyway. At the same time, Li Yu also noticed that whether it was the connection between Wang Guo and Wang An, or the connection between Cui Yu and Wang An, an important person was mentioned, but Cui Yu was vague about this person. Li Yu asked a few times, but Cui Yu smiled and didn't answer, just said that he would know.
