The Prodigal Son of Zhenguan

"Hmm?" Li Fu looked at Li Lizhi.

Li Lizhi whispered, "Dr. Lu called you."

Li Fu looked up and looked at Lu Deming.

"What do you think, Your Highness?" Lu Deming asked.

He saw Li Fu in deep thought and thought that Li Fu was thinking about the course he taught, so he asked this question.

Li Fu pretended to be in deep thought and whispered to Li Lizhi.

"What did Dr. Lu say just now?"

Li Lizhi understood and said secretly, "The king won the country with frugality and lost the country with extravagance."

Li Fu nodded, this one.

"Looking back at the countries and families of the ancient sages, success comes from diligence and frugality, and failure comes from extravagance." Li Fu responded, "I think Dr. Lu is right. The fall of the former Sui Dynasty should be learned from it."

"Since the lesson is learned from the fall of the former Sui Dynasty, what does King Jingyang think the current dynasty should do?" Dr. Lu asked.

"Now that your majesty has set an example by abolishing the inner court and being frugal, the court should also adhere to frugality in handling all affairs, resolutely oppose waste, oppose ostentation, and compare extravagance, resolutely resist hedonism and extravagance, and resolutely prevent going through the motions. We must truly be frugal and start and end well.

Officials of our Tang Dynasty should insist on suffering first and enjoying later, and set an example.

If this frugal style is not grasped tightly, grasped in reality, and grasped infrequently, it is equivalent to grasping in vain."

.......

The whole pavilion was silent.

Lu Deming didn't know how to react for a moment after listening to Li Fu's words.

But the words of King Jingyang sounded very encouraging.

Moreover, this is a very good word.

After a long time, Lu Deming clapped his hands and laughed.

"Your Highness's words are like drinking fine wine." Lu Deming praised generously.

And the three children just stared at their uncle.

Uncle Wang's words were full of vigor.

Moreover, even if he didn't hear what Dr. Lu said, as long as he mentioned it, he would speak eloquently.

"Uh..." Li Fu hesitated for a moment and stretched out his hand to stop him: "Don't drink yet, the three little princes have to continue their studies, I won't disturb them here, Dr. Lu, please continue."

Li Fu hurried away.

Three children are studying, he is here, Dr. Lu also counts him in.

If he asks more questions, Li Fu will not chat.

Leaving the pavilion in the backyard, Li Fu breathed a sigh of relief.

If he asks again, he will be exposed.

In the evening, Li Chengqian and others finished their class.

Li Tai looked worried.

"Qingque, what's wrong? I felt that you seemed to be distracted since the class." Li Chengqian asked his brother.

"Brother, I was thinking, didn't we go to the fields to work this morning? It's really tiring to carry water back and forth. Is there a way to draw water directly from the canal and irrigate the fields?" Li Tai said.

"You want a new tool to replace manpower, right?" Li Chengqian asked.

Li Tai nodded seriously.

"Let me think about it." Li Chengqian thought seriously.

Li Tai was also thinking.

Li Lizhi looked at her two brothers.

"Brother, fourth brother, when we came here, we saw a waterwheel by the river." Li Lizhi reminded.

Li Chengqian clapped his hands.

"Yes! There is a waterwheel!" Li Chengqian said: "There is a waterwheel by the river!"

"But by the canal..." Li Tai's eyes lit up halfway through his words: "Yes! Waterwheel!"

Li Chengqian and Li Tai looked at each other.

"Go find Uncle Wang!" The two of them ran to Li Fu's yard at the same time.

Li Lizhi hurried to catch up.

Li Fu was in the courtyard of the study, sitting in the corridor reading a book, with fruits and tea on the low table next to him.

He lay here, crossed his legs, holding a book in his hand, leisurely.

"Uncle Wang!"

As soon as he entered the courtyard, Li Chengqian and Li Tai began to call Li Fu.

Li Fu put down the book in his hand, looked at the gate of the courtyard, and sat up.

"What's wrong?" Li Fu asked, "Have you finished your class?"

"Yes, just finished the class." Li Chengqian said, "Uncle Wang, we just thought of something."

"Tell me slowly." Li Fu asked the children to come over and sit down in the corridor, and asked Xiaotao to get them cups and pour some water.

"Uncle Wang, it's a waterwheel!" Li Tai's little face was full of excitement, his fists clenched, and his eyes stared at Li Fu: "I was thinking, when we went to irrigate the farmland in the morning, is there any way to save effort and let the water go directly from the canal to the farmland? Li Zhi said that there was a waterwheel by the river, so can we also build a waterwheel by the canal to draw water from the canal to irrigate the farmland."

Li Fu laughed when he heard it.

"Not bad, very good." Li Fu reached out and stroked Li Tai's head: "You can go because of the difficulties you faced in the morning.It's great to think of a solution, and it's even better that you can think of a waterwheel in the end. "

"You are sensible." Li Fu looked at the three children in front of him with emotion.

It's true that Li Shimin's several legitimate children are all excellent.

Even Li Zhi, who was not very prominent in the competition for the throne later, was too excellent.

Li Zhi's brilliance was partially covered up because his wife was the only female emperor in the dynasties, so he was looked down upon by many people.

"That means, can a waterwheel be built next to the canal?" Li Chengqian asked seriously.

There is still a gap between theoretically possible and practically possible, so I have to ask Uncle Wang if this is really feasible.

"Yes, of course." Li Fu said: "The canal was repaired last year and put into use after it was repaired. The waterwheel has not been built yet. However, the canal is not over yet and it still needs to be repaired. "

"But as for the waterwheel, you can study it. It's the homework that Uncle Wang left for you." Li Fu said with a smile.

He looked at Xiao Tao.

"Xiao Tao, go to the study and find a book." Li Fu said, "Go find the "Zhuangzi·Outer Chapter·, Heaven and Earth Chapter" that I read before, and "Three Kingdoms·Wei Zhi", these two books, give them."

"Yes." Xiao Tao responded.

Xiao Tao followed Li Fu from childhood to adulthood, and she was also able to read and write.

After a long time, Xiao Tao came out of the study with two books in her hands, which were exactly the two books that Li Fu mentioned.

"Give them to them."

Xiao Tao handed the two books to Li Tai and Li Chengqian.

"It's still a while before dinner. While it's still light, you two can look through the books here. "Li Fu smiled and said, "The water wheels on the riverside today are all handed down from the Han Dynasty. Although they are finished products, there is still room for improvement. Uncle Wang's homework for you is to find out the origin of the water wheels, and then think about whether there is room for improvement in the water wheels."

"There is no rush for this matter. You can take your time to find and think about it. "
