Meng Kexin took out the book "Advanced Electrician" and handed it to Meng Weiyuan, "Dad, this is a book about the wiring back then. Take it and have a look."

Meng Weiyuan took the book and said confidently, "Xin'er, you may not know this, but before your father joined the army, he was the village electrician and is very knowledgeable about wiring issues. However, you can let your brother read this book so that he can also learn about electricity."

Meng Weiyuan casually handed the book to Meng Kehan, "Han'er, take a good look at the contents."

Meng Kehan took it, opened it and looked at it, but those words knew him, but he didn’t recognize those words!

"Daddy, what's written in this book? The words are missing parts, I don't recognize a single word."

Meng Weiyuan then remembered that the characters in the book were modern simplified Chinese characters, which the people here certainly did not recognize. He glanced at Qin Wanying and an idea suddenly popped up in his mind.

She, Qin Wanying and Meng Kexin all traveled from the modern era and have received higher education. She asked Qin Wanying and Xiner to open a primary school here to teach modern writing and arithmetic.

Meng Weiyuan told Qin Wanying his idea. After hearing it, Qin Wanying's eyes lit up and she thought it was a good idea.

So, the two began to prepare.

They found an empty house in Hangu Pass, cleaned it up briefly, and used it as a classroom. Then they bought some desks, chairs, blackboards, chalks and other teaching supplies.

When all preparations were complete, Meng Weiyuan gathered all the generals at Hangu Pass. He announced, "Generals, anyone with a child of school age, even if their parents have to travel far away, may come here and receive free instruction in modern literacy and arithmetic."

Upon hearing this, the generals' faces lit up with surprise, their eyes gleaming with intense interest. Without hesitation, they each brought their children to enthusiastically sign up.

Before long, the originally empty primary school was packed with students who were full of vitality and thirst for knowledge.

Qin Wanying and Meng Kexin walked into the classroom enthusiastically and stood at the podium.

"Students, today we are learning Modern Chinese," Meng Kexin said. "Modern Chinese is our country's common language and a tool for communication. Everyone should study hard and master this language."

"Teacher, why do we have to learn modern Chinese?" asked a little boy.

"Because modern Chinese is our country's official language and the tool we use to communicate," Meng Kexin said, "If we can't speak modern Chinese, it will be difficult to communicate with others and understand the outside world."

"Teacher, I understand," the little boy said. "I will study modern Chinese well and go out into the world."

"Okay, students, let's learn a new Chinese character," Qin Wanying said. "This character is '人'. Look, does it look like a person standing there?"

"Like!" the children answered in unison.

"Yes, this Chinese character is '人'," Qin Wanying said. "'人' is the most important word in our lives because each of us is an individual. We must learn to respect ourselves and others."

"Teacher, I understand." A little girl said, "I need to learn to respect myself and others."

"Okay, classmates, let's play a game," Meng Kexin said. "I'll say a Chinese character, and then everyone will use it to form a word."

"Okay!" the children answered in unison.

"People." Meng Kexin said.

"The people," said a little boy.

"Humans." said a little girl.

"Talent." said a little boy.

"Character." said a little girl.

……

"Well, students, you all speak very well," Meng Kexin said. "Modern Chinese is a very interesting language. Everyone should study hard and master it."

"Teacher, we will study hard." The children answered in unison.

"Next, we're going to start learning arithmetic," Qin Wanying said. "Arithmetic is a very important subject in our lives. It can help us solve many practical problems."

As she gently waved her arm, snow-white lines quickly extended across the blackboard.

First, a large "1" appeared before everyone's eyes, followed by the neatly arranged numbers from 2 to 9, and finally, a rounded, full "0." These simple 10 numbers seemed to be given life, shining with a unique brilliance on the blackboard.

Then teach the children to recognize these ten numbers, and soon the children will remember them.

Then Qin Wanying wrote an arithmetic problem on the blackboard: "2+3=?"

"Classmates, who can tell me the answer to this question?" Qin Wanying asked.

A little boy raised his hand: "Teacher, I know, 2+3=5."

"That's right, very good," Qin Wanying said. "Then who can tell me why 2+3=5?"

The little boy thought about it and said, "Because 2 apples plus 3 apples equals 5 apples."

"Excellent! You're very smart," Qin Wanying said. "Let's look at another question: '4-1=?'"

A little girl raised her hand: "Teacher, I know, 4-1=3."

"That's right, very good," Qin Wanying said. "Then who can tell me why 4-1=3?"

The little girl said, "Because 4 apples minus 1 apple equals 3 apples."

"Excellent! You're very smart," Qin Wanying said. "Classmates, that's what arithmetic is all about. It can help us solve many practical problems. Everyone should study hard and master this subject."

"Teacher, we will study hard." The children answered in unison. Under their guidance, the children developed a strong interest in modern characters and began to actively learn and explore the mysteries of characters.

Their teaching not only enables children to master knowledge, but also cultivates their interest and ability in learning, laying a solid foundation for their future development.

These young students all listened to the two teachers' explanations with full concentration and focus.

They are like long-dry land longing for rain and dew, greedily absorbing the nutrients of knowledge.

It is gratifying that after just a few days of study, many students have successfully mastered some basic knowledge and demonstrated a strong desire to further explore knowledge.

Meng Kexin was very happy, "Dad, Mom, we have successors to Hangu Pass!"
