Xu Fenglei looked at the four newly admitted students in front of him, and said in a deep voice:

"There is not much knowledge for a teacher, only the Book of Changes."

"The Book of Changes, the head of the group of scriptures, is written by the ancient sages who observed heaven and earth and combined with their own understanding, which contains the principle of the operation and emergence of all things in heaven and earth."

Of course, it also contains the way of being a minister and a king; What a gentleman does, what a villain does. ”

He paused for a while, and the children all listened attentively.

Li Shimin and the eldest grandson Wujian also listened attentively.

Although they believed that Xu Fenglei was indeed a master, they also wanted to see his teaching standards.

This "first lesson of school" began so casually.

"In the past, Confucius once wrote a biography for the Book of Changes, and he was also very fond of divination, and in his later years, he was very complacent that he had divined for so many years, and seventy percent of them should be fulfilled accurately."

Xu Fenglei sat down safely, and said,

"As a teacher, I will not teach you divination and fortune-telling, but only teach you how to be a monarch and a minister, how to distinguish loyalty and treachery, and the most important thing is to learn to think independently."

"Whether or not to think independently is the dividing line between mediocrity and talent, and I hope that my disciples can produce their own understanding in the process of learning and become talents, rather than mediocre talents who follow the textbook and follow the teachings."

"Do you get it?"

The four disciples all nodded.

Even the youngest Li Lizhi nodded her head ignorantly.

"This teacher, I've found the right one."

The eldest grandson Wujian winked at Li Shimin and whispered.

Li Shimin smiled slightly.

"How can my vision be bad?"

He was a little proud,

Just a sentence of "for the monarch and the minister, distinguish between loyalty and treachery" is enough to be qualified to be the teacher of his children.

And the words "independent thinking" in the back made Li Shimin's heart bloom!

Yeah!

That's such a precise word, that's what I want!

At this moment, Li Shimin's heart has already let go of half of it.

"It's still early, so I'll explain to you the first hexagram of the I Ching."

Xu Fenglei glanced at the sky and said.

"The first hexagram, that is, the Qiangua, is the sky."

"Here, get me a pen and paper and a sketchpad."

He beckoned, and Li Qingquan immediately got up and brought him three things.

Xu Fenglei fixed the paper on the drawing board, and with a wave of pen and ink, he wrote from the bottom to the top of the drawing board:

—(Yang)

--(Negative)

"One horizontal is yang, and one in the middle is yin, this just needs to be remembered, and it will be often used as a teacher in the future."

Xu Fengleidao,

"It's easier to explain the I Ching with images."

Li Qingquan gave pen and paper to several children.

"Qingquan, give us a copy too."

Li Shimin beckoned.

He has nothing to do at the moment, so he might as well listen to the lecture.

Since he came to Rong at the age of sixteen, he has either been fighting or on the way to war, and he has not read or studied for a long time.

Taking advantage of this opportunity, Li Er also wanted to enrich his brain.

"Okay."

Li Qingquan sent pen and paper to Li Shimin and his eldest grandson.

They also obediently copied their notes and became good students.

Xu Fenglei bowed slightly, and then drew six horizontals from bottom to top on the drawing board:

—

—

—

—

—

—

"This, that is, the Qiangua, is also called Qianweitian."

Xu Fenglei threw down the brush and explained,

"Why do these six horizontals represent Qian, and represent the sky?"

"When we want to look at the sky, we all look up at the sky, but our ancestors are amazing, they will substitute themselves into the 'heavens'."

"What are you doing when you're the sky?"

Li Shimin was stunned, and the eldest grandson Wujian also fell into thought.

"Look down!"

Li Chengqian replied without thinking.

Li Shimin glared at him, and Li Chengqian shrank his head in fright.

"That's right!"

Xu Fenglei snapped his fingers and boasted,

"Cheng Qian's head is very bright!"

"That's right, if I were heaven, I would be looking down! The nature of heaven is to look downward. ”

Li Chengqian was praised by him like this, and his eyes suddenly lit up.

He looked at his father sharply, and although he didn't speak, his meaning was already obvious—

Father, I'm not wrong! Master said I was right!

Li Shimin: "......"

"For example, you are an older brother now, and if you look down, you will take care of your younger siblings."

Xu Fengleidao,

"You are the father, and you take care of a large family; You are the county commander, and you govern the people of a county. ”

"You are the governor of the state, and you will rule over the people of a state; If you are a minister, you will manage all the affairs of the world, and if you are the son of heaven, you will be in charge of all directions in Kyushu. ”

"When you do this, you are looking down, you are consistent, and you have a 'natural' nature."

The students all nodded their heads as they listened to these easy-to-understand words.

Li Er and his wife are already the head of the jaw.

"But nowadays, people often go against the sky."

Xu Fenglei said again,

"You are the county commander, you just want to climb up and become the prefect."

"You are the state pastor, you want to enter the center of the court; When you become an important minister, you want to tilt the power towards the government and the opposition, or even become the emperor! And when you become an emperor, it's even more outrageous, if you want to be an immortal, you have immortality. ”

"If you keep looking up, you won't look down, and this is the root of suffering, and it is also the foundation of self-destruction. Man, once he has fallen into it, his desires are endless, he has lost his 'natural' nature, he is detached from the masses below, and all he has is nothing but a castle in the air. ”

Li Shimin's heart was shocked, the pen in his hand also hovered, and a drop of ink fell on the paper.

He was shocked by these words, and his heart rippled.

"The nature of 'heaven' is strong and firm."

Xu Fenglei didn't pay attention to Li Shimin, and continued,

"If you are in your position, you will seek your job, and if you do not seek anything else, you will concentrate on it, that is, 'chastity'!"

"The word chastity, as a teacher, I hope you will understand it well, if you can be chaste, then there is nothing in the world that you can't do."

Boom.

The students took quick notes.

They may not be able to fully understand it at the moment, but the concept is instilled and the framework is built, and as they grow, they will naturally become more and more experienced.

"...... Chastity"

Li Shimin muttered in his mouth and fell into a long exam.

"'Natural' nature is full and all-encompassing."

Xu Fenglei said again,

"The first sentence of the Book of Changes says, Tianxingjian, a gentleman is constantly striving for self-improvement."

"What does it mean to be self-reliant? In fact, it is always learning, always improving, and never being complacent. ”

"To sum it up in six popular words, it is 'live to be old and learn to be old'."

As he spoke, he smiled and pointed at Li Shimin.

"Look at your father, he has mastered his nature, and he is obviously teaching you as a teacher, but he is also humbly listening and taking notes."

Xu Fenglei quipped,

"Even His Royal Highness the King of Qin, the Tiance General who has high achievements and is both civil and military, has not stopped learning."

"You have to learn from your father!"

The children turned their gaze to Daddy in unison.

The eldest grandson Wujian also put down his pen and looked at Li Shimin.

Li Shimin's old face flushed: "......"

This is praised, and I am embarrassed......
