Gu Qing dug a pit behind the village with his own hands to bury the old donkey. Gu Qing's second son Gu Xue looked at the old donkey and asked in a low voice, "Father, why did it die?"

"It's life span." Gu Qing picked up his four-year-old second son, "It's your master's grandfather and his father's old friend. It brought me to Chang'an with nothing. Your master's grandfather is another nostalgic person, so I went to accompany your master's grandfather."

"Oh." Gu Xue nodded in a daze.

After burying the soil, Gu Qing carved the letters on the stone tablet with his own hands, the tomb of the Gu family's mount.

Just six simple words: Give this donkey an identity and let others know who the tomb belongs to. Perhaps there may be descendants of the Gu family to sacrifice to the future.

Gu Xue is a child with a talent for mathematics and has a high understanding of learning, unlike Gu Xiao. Gu Xiao likes money, and Gu Xue seems to be not interested in money. Her youngest son Gu Ling has just learned to walk.

"Father, do you think you will die in the future?" Gu Xue still pestered Gu Qing.

Gu Qing whispered, "Why do you think people are alive?"

"Life means eating, sleeping, and reading?" Gu Xue answered very cutely.

Gu Qing smiled bitterly and said, "In fact, people rely on the environment to survive. People consume the environment. The development of civilization depends on human wisdom. However, human survival depends on the environment. No matter how civilization develops, we must always leave a living environment for human beings. Just like you said that people need to eat and sleep, this is the same truth. Therefore, the first thing that the development of civilization must consider is the changes in the environment."

Gu Xue pouted and said, "Oh, I didn't understand."

"It's okay, I'll understand it later." Gu Qing said to him, "Go, go and accompany your master and grandfather. He is in a bad mood."

"Okay." Gu Xue nodded obediently.

Fan Jian and Zhang Yugong came back from school with Gu Xiao from left and right. When Gu Xiao returned home, he threw away the bag of books.

"Dad, I've gone to play." Gu Xiao left happily after saying that.

"Master of the family, something came from the palace." Fan Jian came to Gu Qing and whispered, "Li Chengqian made his eldest son Li Xiang the crown prince, and said that the prince would also want to take the head of the family as his teacher. This was the one in the village who went to the palace and Li Chengqian issued an order."

"This father-in-law wouldn't say hello to me in advance." Gu Qing muttered.

"Then we..." Fan Jian said hesitantly.

"Be prepared, I will accept this disciple." Gu Qing said, "The father-in-law doesn't expect Li Chengqian to give him too much hope. He wants to make a second-hand preparation. Li Chengqian doesn't seem to be able to count on him, so he hopes that the next generation will have His Highness and a prince first. It's a headache."

Xiao Siezi and Gao Yang also returned home and heard Gu Qing discussing this and asked curiously, "Brother Gu Qing, do you think the emperor's son wants to take you as his teacher?"

"Yes." Gu Qing said helplessly.

What kind of evil is it? Why are the royal children sent to their homes one by one? Are they addicted to eating and drinking for nothing?

"Then Brother Gu Qing is going to be promoted again? The prince's teacher, what an official?" Xiao Yizi was confused.

"It's okay to be a teacher, but he doesn't care about being an official." Gao Yang said, holding Xiao Yizi's hand, "Mingda, let's go make cakes, and I don't pay much attention to him."

Xiao Yizi is very clear about her elder sister's thoughts. Although Gu Qing and Gao Yang often quarrel with each other, the elder sister has a deep relationship with Gu Qing, and the more she fights, the better the relationship is.

Gu Xiao and Zhang Jiuling and others were fishing by the river together.

Fang Chengxian threw down the fishing line and said, "I heard from my father that they often come back here to fish."

Gu Xiao put the fishing rod aside and had no intention of fishing. He picked up the stones on the ground and played with water.

"You said that car is so smelly, will it be stinky in Chang'an when it is built in the future?" Zhang Jiuling asked in confusion.

"It's right." Gu Xiao said, "I remember my father said that science is the first element of development, science, and science is the cornerstone of civilization. But the continuous development of science and technology has followed the explosion and growth of population. You have also discovered that there are more and more children in Chang'an now. In the future, there will only be more and more people. People are wise. The development of population and the development of science and technology are coordinated, but the environment is always on which people rely on. The resources in this world are limited, but the population is growing. If you build too many cars, it will cause pollution."

"We are fish in the river. If the river water is dirty, we will not survive. There are too many fish and there is not enough water. However, my father said that he should know this kind of thing, so he will control it and don't worry."

"Technology, population, environment, civilization?" Zhang Jiuling listened to Gu Xiao's words, "These are all things that the academy has not taught. Others can be understood. Technology is related to the physics we learn today. Is it the so-called science?"

"The same meaning is almost the same, to put it bluntly, it will be wise." Gu Xiao nodded.

"So amazing." Yang Zhao said, "Gu Xiao, can you learn something that the academy cannot learn at home?"

"Of course, why don't I learn from my father in the future and I will teach you after I learn it. The tuition fee is not too much. I will give you fifty texts in one lesson." Gu Xiao said with a smile.

"Your father has the same virtue as you, you need money." Fang Chengxian glanced at Gu Xiao.

The next day, Li Chengqian's son Li Xiang came to the Gu family.

Gu Qing looked at the prince of Li Chengqian and said indifferently, "Your father arranged you to me to learn something, tell me what you want to learn."

Gu Qing did not salute, but Li Xiang bowed first, "Students pay homage to the teacher."

I was a little surprised to see him saluting.

Li Xiang continued, "Students heard from their youngest that the teacher was a talented and stubborn person, the most famous strange and strange thing in the Tang Dynasty. Teachers can not only make the people of the Tang Dynasty rich, but also learn from ancient and modern times. It was the academy built by the teacher that made the court today have so many ministers, and it is the teacher's..."

"Okay, okay, stop!" Gu Qing interrupted him. This kid was so good at flattering at such a young age. He was really a rare talent.

"Then I won't say it." Li Xiang took a step back.

"Go and pour me a cup of tea." Gu Qing said.

"Okay." Li Xiang obediently went to pour tea.

"Go and get me some snacks."

"good."

"Press my shoulders."

"good!"

...

The palace maids and eunuchs who accompanied the prince were stunned when they saw Gu Qing serving the prince in front of him and behind him. Isn’t this Gu Qing really afraid that Li Chengqian would come with his troops to kill him?

Gu Qing cleared his throat, "Do you know why I asked you to do these?"

"Students don't understand, but students know that it makes sense for the teacher to let students do these."
