Li Buqi did not answer everyone's questions directly, but said: "Let me ask you one more question, if you have an answer to this question, whether the latter two things are in line with the Dao will also have an answer." ”

"Suppose in an extreme case, there are only three people left in the world because of the famine, one is yourself, one is your old mother, and the other is your pregnant wife. But if you only have food that can keep two people alive, how will you divide it? ”

A Xiucai said: "Naturally, I gave food to my mother and wife." ”

Li Buqi said: "Then you will starve to death, and your mother and wife will not only lose your protection and eventually die in the mouth of wild beasts, but they may also be unable to continue to get food and will soon starve to death." Not only your family, but also Huaxia has been cut off from this bloodline. There are three unfilial pieties, and no queen is great, not to mention that my Chinese blood is cut off, and when you arrive in Huangquan, Chinese ancestors like the Three Emperors and Five Emperors will not spare you. ”

………

And they were dumb. Li Buqi said: "There are several possibilities, I will say it for everyone." If you don't give food to your mother, it's unfilial. If you don't give food to your wife, you will also have no heirs, and you will still be unfilial. How do you choose? ”

Not to mention that the brains of scholars are active, after Li Buqi asked, someone immediately asked: "I don't know how to choose?" ”

Li Buqi said very irresponsibly: "I don't know either. But I think through this question, I can understand that the choice of the unknown people and the Huns is not without cause. This is something that a person who sits in the study and has no worries about food and clothing, and can add fragrance to his red sleeves, right? Therefore, if you want to thoroughly understand the knowledge of the sages, you must be immersive. It's just that the era of the sages has been more than a thousand years, and the times have long passed, and they are taken for granted in the study, so the knowledge of the sages can't be learned even if they are fur. ”

The last two examples cited by Li Buqi obviously touched everyone deeply, and they all fell silent for a while. Li didn't give up or was in a hurry, he drank a cup by himself, and at this time, it was Shao Yong, who had been wandering for many years and seen a lot of things in the world, that he was the first to come back to his senses and asked: "I don't know what the official said about learning to learn to swim like a person, how to explain it?" ”

Li Buqi stood up and asked, "Who is good at swimming?" Hands! ”

Immediately, more than twenty people raised their hands. Li Buqi asked again: "Okay." Who doesn't know how to swim at all? Raise your hand now! ”

Now he raised an arm. Li Buqi asked: "The weather is warm, we can do an experiment." Ask someone who knows how to swim to write out their method, and then have someone read it carefully to see if they can swim. ”

A Xiucai with a strong southern accent immediately said: "Officials don't have to try, it's impossible." Children soak in the water every day and can swim without being taught. But if you don't go into the water, no matter how much you say, you will still sink to the bottom once you go. You can't learn to swim just by reading. ”

Li Buqi smiled and asked, "Those who can swim, are you right when you say he said it?" ”

Someone said: "I have also taught others to swim, and it is better to go down and pour a few mouthfuls of water if your mouth is dry." ”

Li Buqi said: "Yes! The sage said that words and deeds are not enough, it can be seen that words are not enough, since the saint has passed away and cannot teach by example, then later students can only test the water themselves. The Master was born first, and then traveled around the world, reading all the world, and only then did he achieve some learning. If you only hide in the study and don't know the world, how can you understand the profound meaning of the sage's teachings? ”

These words made everyone nod their heads, Li Buqi ordered a dish in front of him and said, "Again, if the sage says that this dish is delicious, how do you know how delicious this dish is if you haven't tasted it?" If you were to write about the benefits of this dish for others to see, what else could you write but repeat the words of the saints? What's more serious is that some of the accounts of the ancients are wrong, if you don't personally observe and correct them, but just relay them to future generations, wouldn't it be misleading? ”

Zhang Zai asked: "I don't know if the official can give an example?" ”

Li Buqi said: "'The son of the moth' comes from the Book of Songs, Xiaoya, Xiaoyuan, and its words 'The moth has a son, and the moth bears it'." However, the prime minister of the mountain did not believe him, and personally opened the nest of the moth to observe, and found that the moth caught the moth not as a righteous son at all, but as food for his own offspring. If you believe in the Book of Songs, isn't it a false rumor? ”

Tao Hongjing of the Liang Dynasty in the Southern Dynasty, lived in seclusion in Maoshan Mountain, repeatedly could not be hired, Emperor Wu of Liang often asked him for advice on national affairs, and people called him "the prime minister in the mountains". Tao Hongjing is also a big bull, and he has written many books on medicine, alchemy and metaphysics, and it is estimated that no one in the Great Song Dynasty dares to challenge this bull.

Shao Yong nodded again and again: "The official's words made Yongmao pause. But I don't know what is the solution of building a high-rise building? ”

Li Buqi said: "There is a poem that 'wants to be poor for thousands of miles and go to the next level'. It's just that the high-rise buildings built by the predecessors are only so high, and if you want to go up one floor, you have to build another layer yourself. Can we tear down the ground floor and build another floor with materials? Of course not, we need new materials, and we need materials that were not in the building to build a building. As long as there are materials, this building will be built from generation to generation, and one day it will be as high as the sky, and it will really look thousands of miles away. ”

A Xiucai asked: "The writings of the sages are all-encompassing and meticulous, where can people today find new materials?" ”

Li Buqi smiled and asked: "Since the sages' books explain all the truth, then can you tell me, why can people fly to the sky?" ”

"This is simple, and it is natural to go against the wind."

Li Buqi clapped his hands: "Yes, that's what the book says." But I put a Kong Ming lantern in the house, and the Kong Ming lantern also flew, but there was no wind. What's going on? ”

"Oh, this ......"

Li Buqi said: "Everyone should remember that the two children argued about the day, and the master could not decide. At least this problem is not solved, right? Who's to say it's not learning? I'll make a trick for you, how about you explain it with the truth in the ancient book? ”

Then he instructed Ying'er: "Go and bring the tall glass in the study." Bring another candle. ”

After a while, two things were brought in. Li Buqi put the candle in a bowl to fix it, poured half a bowl of water into it, lit the candle, and then said, "Let's see what will happen to this glass." ”

After saying that, he put the glass on the candle, and after a while, the flame of the candle flickered and went out, and a few people who were close exclaimed: "Huh? How can the water inside the glass not be as high as the outside? ”

Li Buqi handed the glass to Zhang Zai: "You can try it." ”

Zhang Zai repeated it twice, and couldn't help asking, "What is the truth?" ”

Li Buqi said irresponsibly: "I don't know either. Does anyone know an explanation for this situation in ancient books? ”

Everyone looked at each other and eventually shook their heads. Li Buqi picked up the glass again and filled it with water, then turned the quilt over, and immediately splashed the water on the ground. Li Buqi showed the cup to everyone like a trick, then poured water into it, pasted a piece of paper on his mouth, and slowly turned the cup over, but not a drop of water was spilled.

Li Buqi took the cup and showed it to the people, and asked, "Can anyone tell me what this truth is?" ”

Still no one can answer. Li Buqi tore the paper, and the water spilled out with a loud bang. "Everything can arise because of the reason for it. There are so many unexplained things in the world, and it is all knowledge to find out the truth. The old man sent me two sentences, and I will encourage you today. ”

Shao Yong hurriedly said: "Official, please speak." ”

"The world is full of knowledge, and the practice of human feelings is the article."
