More and more people in Chang'an are discussing this matter, not only the rich businessmen who are designed, but also the common people.

Among them, Shu An's name was mentioned again after a month, but this time the call was higher, and more and more people recognized the title of Shu Bansheng.

"Is An Xuangong the reincarnation of a god, and he even knows such secrets."

"Now you can't call An Xuangong, if you want to call Shu Bansheng, this is naturally very human."

"How to maintain health, I don't know if An Xuangong can publish a book, even the princes and nobles have begun to learn health preservation, I don't know if I have a chance."

.........

The voices of discussion sounded, including scholars and people, but the people were more of an emotion.

Shu House

"Student Du Ruhui has seen the teacher!"

As a voice sounded, Shu An couldn't help but shake his head on his face, and sure enough, he guessed in his heart that the most likely person was Du Ruhui.

As for the reason, it is very simple, that is, Du Ruhui and him have a lot of closeness, and there are not a few who value this.

"Say whatever you want."

Shu An said softly, with a hint of flatness in his words, no matter who came from the facts.

Naturally, he won't hide it, and of course he can't let health care become a dispensable thing, so how much to say, this is the need for a sub-office.

"I don't know if the teacher has ever thought about lecturing on health preservation?"

Du Ruhan asked out loud, with a hint of helplessness in his words, he knew that someone else was coming.

If it weren't for His Majesty and many other people requesting, even Du Ruhui wouldn't have the courage to make this request in front of the teacher.

"I'm old, I'm too lazy to go out and give lectures."

Facing Du Ruhui's words, Shu An shook his head slightly, and said slowly with a smile in the depths of his eyes.

Du Ruhui's face drooped suddenly, and he looked listless, but of course, even he was an admirer of health preservation.

Who doesn't want to live a few more years, even if it is Du Ruhui, especially after listening to his son's health preservation.

Even Du Ruhui couldn't help but be taken aback, the reason is very simple, the content of many negative examples above health care seems to be consistent with his own behavior.

This naturally made Du Ruhui feel a little uneasy in his heart, and he had secretly corrected these habits, although he didn't know if it would affect anything, but he felt much better in the past few days.

The change in the faces of these students naturally made Shu An look at it, and he couldn't help shaking his head in his heart, as expected, it was not enough to believe what he just said.

Although he had explained some things to Du Ruhui a long time ago, Du Ruhui obviously remembered it for a while and then forgot about it.

But this is also normal, sometimes you are so busy that you forget about your own things, especially the previous natural disasters.

Even Li Shimin couldn't sleep at night, not to mention these important ministers of the DPRK and China, presumably not much better.

With the introduction of health preservation, he saw that Du Ruhui had changed, and it was obvious that there were many examples in front of him, which made this student panic in his heart.

After thinking of this, Shu An couldn't help but show a smile on his face, and then the voice sounded again.

"Although the teacher no longer lectures, the students of the academy can."

After the words fell, Du Ruhui's eyes lit up slightly, he didn't expect the teacher to plan like this, of course, he also thought of it, the teacher must have used this to hone these students.

There is also paving the way for these students, even if most of the fame belongs to the teacher, but there is still a small part of the fame that will fall on these students.

"Keming took the liberty of asking, don't you know that the teacher's health care can be combined with a book?"

Du Ruhui said slowly, with a hint of expectation on his face, this question obviously asked the voices of many people.

Shu An glanced at the student, Du Ruhui was not as presumptuous as he said in his words, but he also knew Du Ruhui's eagerness in his heart.

In the face of the temptation of longevity, it can be said that no one in this era can resist it, including the student in front of him.

"For the teacher, the health sutra is divided into upper, middle and lower volumes, of which the upper volume has been written."

Shu An said slowly, since he was going to spread his health theory, he was naturally prepared.

The books of this era did not have as many words as those of later generations, such as the Analects, which were only more than 10,000 words.

It seems like a lot, but in the future, any paper will be more than this number, so Shu An divided the original tens of thousands of words on health preservation into upper, middle and lower volumes.

Du Ruhui's eyes showed a glimmer of light, since it was a book, it would be natural, but after the words came to his mouth, this important minister of the court couldn't help but show a trace of embarrassment on his face for a while.

"For what reason do you want to get the paper from the teacher?"

For a while, Du Ruhui felt that his head was a little confused, and many people had hinted that he came to the teacher to ask and inquire about some news.

Du Ruhui naturally knew the abacus of these people, and he definitely wanted to know the content of the teacher's health sutra, and of course he was no exception.

It's just that now Du Ruhui feels that his face is a little unbearable, after all, he can't take things from teachers and the like without reason.

On the other side, Shu An couldn't help but smile slightly when he saw the change in Du Ruhui's complexion, but he didn't expect Du Ruhui to retreat at the last step.

After thinking of this, Shu An couldn't help but feel funny in his heart, but he didn't want to embarrass this disciple.

"This is the first volume of the Health Sutra, if you want it, take it and copy a copy."

Shu An's voice sounded slowly, and at the same time, he took out a bound book from behind him.

This is the inner cylinder he wrote after thinking about it for a long time, which is more of a brief description of health preservation, and there are some examples.

The main thing is to popularize the concept of health care and the relationship between health care and longevity, and the purpose is equally obvious, that is, to adapt the people of this era to the concept of health preservation.

"Teacher...."

Compared with Shu An's crispness, Du Ruhui's face showed a trace of embarrassment.

If there are outsiders here, they will definitely be very surprised, after all, Du Ruhui still has a lot of fame, and he is a confidant of His Majesty today.

In ordinary times, Du Ruhui doesn't have so many emotions on his face, but today's emotions are very numerous, and they are surprising.

"Don't be a child, anyway, you are also one of the teachers and students, those academy students have no master-apprentice status, they can all be passed on, why don't you pass on as a teacher."

Shu An's voice continued to sound, this is the so-called authorities are obsessed with bystanders, and now Du Ruhui is in this state.
