The Prodigal Son of Zhenguan

In the kitchen yard, Tiezhu was busy with Liu Niang's work.

The doorman hurried to the yard.

"Tiezhu, stop working, the master is looking for you." The doorman said, "The master is waiting for you at the door, hurry up."

After a series of urging, Tiezhu hurriedly found a rag to wipe his hands.

Seeing this, Liu Niang hurriedly got up and took a clean cloth towel.

"Wipe it clean, don't lose your manners in front of the master." Liu Niang handed the cloth towel to Tiezhu.

Then she looked at the doorman again.

"Do you know what the master is looking for Tiezhu for?" Liu Niang asked.

The doorman shook his head.

"I don't know yet, but it seems that the master and the prince are going out for a while, but I don't know where they are going." The doorman responded.

Tiezhu wiped his hands, tidied his clothes, and then hurried out with the doorman.

Li Fu and Li Chengqian were waiting at the door.

As soon as Tiezhu came out, he quickly apologized to the two.

"Okay, stop wasting time, let's go together." Li Fu said.

Tiezhu was very tactful and wanted to take the four treasures of the study from Li Fu and Li Chengqian.

Li Chengqian also handed them directly to Tiezhu.

Not to mention, the inkstone was also very heavy, fortunately he added a little water when grinding the ink.

The three walked to the house where Lu Deming lived.

"Dr. Lu, are you home?" Li Fu asked standing at the door.

The place where he lived was small, which was the advantage. If he shouted at the door, the people inside could hear him.

"Your Highness, please come in." After receiving the order, the people in the yard hurried to open the door for Li Fu.

"Why are you closing the door in broad daylight?" Li Fu laughed.

He took the two children into Lu Deming's residence and sat down on the stone bench in the yard.

Fortunately, the weather is hot now, otherwise the stone bench would be cold to sit on. It would be uncomfortable to sit on it without anything to cushion it.

Lu Deming came out of the house and said as he walked: "The people in the village here are very enthusiastic. They sweep outside every morning. Originally, I asked two servants to clean the door of this place, but after those people in the village knew that I lived here, they came to do the work early every morning, which made me feel embarrassed."

"Just let the people at home go out early in the morning to do the work, and then close the door and hide for a while."

"It also saves them from quarreling at the door because of the work."

Lu Deming also sat down at the stone table.

Tiezhu stood aside, holding the four treasures of the study in his hand.

"Tiezhu, don't hold it, put it on the table." Li Fu said to Tiezhu on the side.

Lu Deming was puzzled by this posture.

"What is Huairen going to do?" Lu Deming asked.

He thought Li Fu had brought some drawings over again, but after the four treasures of the study were placed on the table, the paper was blank.

"I was originally thinking of talking to Cheng Qian about Zhuangzi's school, but later I thought, it's better to talk to you." Li Fu smiled and said, "I packed up the things and brought them here."

Lu Deming smiled helplessly when he heard this.

"If you want to use it, there are also some in my place. You don't have to waste your time."

Li Fu also smiled and didn't say anything. He didn't think much at the time and brought it here. In fact, it was the same to give it to the doorman and let him take it back to the house.

"Dr. Lu, before talking about Zhuangzi's school, there is one more thing I want to ask your opinion." Li Fu said, and then he pulled Tiezhu to him: "What do you think of this child?"

Lu Deming looked at Tiezhu.

Tiezhu bowed his hands quickly.

"I am Chang Yi, and I am here to meet Dr. Lu." Tie Zhu bowed respectfully.

Tie Zhu's full name is Chang Yi, and Liu Niang's husband's surname is Chang. It is said that after the couple got married, when she was pregnant with Tie Zhu, she thought that she would have many children in the future, and then they would be named Chang Yi, Chang Er, and Chang San, regardless of whether they were boys or girls.

Unfortunately, after Chang Yi was born, when the child was less than two years old, Liu Niang's husband died of illness.

"She is quite decent." Lu Deming nodded slightly: "I wonder what you are thinking, my dear?"

"This child has been with me since I was in the manor. She has been smart and polite since she was a child. She is a good seedling. Although my family was not rich at that time, we still thought that if she had talent, she should not be wasted. Therefore, we sent her to school. After enlightenment, she has been studying in the school. Later, she went to Chang'an City and found a college in Chang'an to study in the college."

"I brought him to see Dr. Lu today because I want Dr. Lu to take a look. If he likes her, I will keep this child as a disciple and let him serve Dr. Lu."

"So that's how it is." Lu Deming nodded: "Then, I will test this kid today."

Hearing Lu Deming say this, Tiezhu smiled happily.

"Yes." Tiezhu hurriedly bowed.

"Tiezhu, if you pass this test, you will be the disciple of the great scholar Lu Deming. Seize the opportunity and use what you have learned." Li Fu urged.

"Yes, my lord." Tiezhu responded excitedly.

It goes without saying what it means to be a disciple of Dr. Lu Deming.

Following Dr. Lu, even if you just serve tea and water to Dr. Lu, you can learn more than what you can learn in the school.

"Then let's see how you are at math. "Lu Deming said slowly.

Enlightenment is the foundation of a child's study. Studying is like building a house. Accumulating little by little, the soil becomes a mountain, and wind and rain arise there. The water becomes an abyss, and dragons are born there.

The Imperial College is divided into six academies, four schools, the Imperial College, the Imperial College, the Law School, the Book School, and the Mathematics School.

But these are divided into different categories after enlightenment.

In the Mathematics School, the first year of study is "Sun Zi Suan Jing" and "Wu Cao".

After coming to Zhuangzi, Lu Deming heard a lot of Li Fu's thoughts on teaching children to read. Since Chang Yi was born in Jingyang Wangfu, he would naturally be influenced by it.

In addition, Lu Deming also has certain achievements in mathematics.

"Your husband said that you have been studying since childhood, so let's talk about the content of "Sun Zi Suan Jing". "Lu Deming gave a relatively basic test question.

When learning mathematics, Sun Zi's Mathematical Classic is an indispensable classic.

"Mathematics is the end of the four seasons and the beginning of the ancestor of all things..." Tiezhu began to express himself: "In any method of calculation, first recognize its position, one vertical and ten horizontal, a hundred standing and a thousand rigid, a thousand and ten facing each other, a million and a hundred equivalent..."

Tiezhu recited Sun Zi's Mathematical Classic skillfully, and then began to analyze the meaning of the content, and also mixed in some of his own views and opinions.
