While thinking about what happened to Gongzheng in her mind, she didn't show a trace on her face, but her mouth was still talking to Gao Chi: "The Heavenly Bull can make two sounds, one is creaking like sawing wood, and it stops rhythmically, and the other is a subtle humming sound, you catch it, it panics and runs for its life." Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 info And this thing is so stupid, when you go to catch it, your hand touches its body, and it doesn't spread its wings at all and flies away, and it always panics when it is caught. But be careful of being touched on the head, because this thing can even bite through wood, let alone human hands, if you don't pay attention to being bitten, it hurts!"

"My second brother has caught this thing before," Zhang Zhaohua said: " Feed the chicken, the chicken likes to eat this thing, he has such a big can, pick down one with the wire and put one into one, he knows how to play better than others, for example, find a thin line, one tied to the neck of the bull, one head with the hand to lead, why is this thing called the cow, but it is really a bit like a cow ploughing the land when it crawls, but often it struggles to fly up without climbing a few steps, but it is more fun to fly, because it has a rope around its neck, just like flying a kite, you see it flies high and pulls the rope, and flies back with a light pull, my second brother's most capable place is to put five bulls on one hand, and can also command this thing to fly in different directions。 ”

Zhang Zhaohua's eyebrows fluttered when he spoke, and Gao Chi and the people who served in the garden laughed.

"Listening to you, it's really vivid," Gao Chi said, "Why did you have so much fun when you were a child." ”

"You were born in a heavenly family, you don't have much fun just reading," Zhang Zhaohua took a sip of soup, put down the bowl and pointed to the palace maid who served casually: "You ask her, I see that she has calluses on her hands, and she has done a lot of farm work, you ask her if she has also caught these insects and fed them to the chickens." ”

Gao Chi looked over, and the palace maid hung her head slightly, as if she knew that she was referring to her, so she said: " Back to Niangniang, the slave also caught a lot of insects when she was a child, and naturally also caught the cow, in addition to the way Niangniang said that the game of Saifei, the slave maid's hometown also has a game of fishing for the bull, which is similar to the race to the fly, the method is to put water in the basin, put a small piece of fish, perforated tie, and the other end is tied to the horn of the bull, the small piece is covered on the bull, and then the bull is placed on another small wooden strip, floating on the water, the cow is surrounded by water, cramped and restless, and frequently waves the tentacles, similar to fishing, so interesting. ”

"Bugs also have such a novel way to play," Gao Chi said: "When I was a child, I just dug out ant holes, so you also know that the heavenly cow is a pest?"

"As the lady said," said the maid, "this thing is indeed a pest, which corrodes the trees and harms the crops." ”

"It seems that I am indeed lonely," Gao Chi said: "I still read a lot of agricultural books, and I don't remember that there is anything written in the book." ”

"If you say this, I will refute you-" Zhang Zhaohua put down his chopsticks and said very seriously: "Let's talk about the past and the present, how many books are written about agriculture in the Eight Classics, that is, a book of "Qi Min Yaoshu" is well known, the value of this book, I think it is much higher than many so-called esoteric academic treatises, but unfortunately the world always thinks that agriculture is very vulgar, and the root is just because Confucius did not teach crops, and he also opposed Fan Chi to learn crops. ”

"If one day," Zhang Zhaohua said: "If you can exchange the 10,000 words for the owner's tree planting book, there will not be so many sour and rotten Confucian students in this world. ”

Zhang Zhaohua said a total of two points, one is that the world is so-called agricultural vulgarity, and there are few books on agricultural affairs. The second point is to refine the truth of the knowledge of things in agriculture, to really obtain knowledge on the one hand, it is necessary to explore the principles and laws of things, it is necessary to "bow down", to see and touch in person, the truth on the paper is on paper after all, the deeper you look at the ground, the more detached you from reality, Gao Chi is like this, and he still does not know that the longhorn is a pest.

Gao Chi was stunned, and said for a long time: "If you really exchange the 10,000-word Pingrong policy for the owner's tree planting book, it must be the most unspeakable sorrow of this person." ”

"But what you said about learning about things," Gao Chi said, "It's really wonderful to use it here!"

Zhang Zhaohua was also greatly surprised, so he said: "Isn't it the meaning of studying things to gain knowledge?"

"How can you be so sure," Gao Chi asked her instead, "You know, before Cheng Zhu, Gewu Zhizhi didn't mean what you said. ”

According to Gao Chi, the word "Gewu Zhizhi" appeared in the book "University" but did not make any explanation after it, so its true meaning has always been controversial and different opinions, for example, Zheng Xuan, the earliest annotation of the Eastern Han Dynasty, interpreted it as the occurrence of things, which is known and liked by people, and "zhi" is the meaning of coming, that is, "if it knows the good, it will come to the good." If they know the depths of evil, they will come to evil things. This statement continued into the Song Dynasty, until Cheng Yi and Zhu Xi, as well as Sima Guang and Lu Jiuyuan, stood up and put forward a new point of view.

"Cheng Yi Cheng Hao and Zhu Xi's views are very similar," Gao Chi said: "I think that the knowledge of things is to exhaustively study the truth of things, resulting in the ultimate intellectual accessibility." That is to say, it is not enough to know the truth of a thing, but we must continue to study, and the deeper we delve, the more we will find that the truth of things will not be exhausted, and the knowledge will not be exhausted. ”

Zhang Zhaohua was overjoyed and said: "That's what I mean!"

It is said that Zhu Cheng's theory of science harms people and how to do evil, but you see, the truth of learning from things is explained so well - in Zhang Zhaohua's cognition, things must be constantly studied and studied, no matter whether it is the study of science or humanities, the more in-depth the investigation, the more you can discover and grasp the laws of things, and you will also obtain deeper and higher level of knowledge.

"Zhu Cheng's point of view," Gao Chi hesitated: "In the Song Dynasty, it was actually not the mainstream. That is, at the end of the Song Dynasty and the former Yuan Dynasty, it was gradually taken seriously, and now, since the imperial grandfather has determined that the imperial examination is broken from the four books, all Confucianism is only the four books annotated by Zhu Xi. ”

"I reserve the right to question Zhu Xi's other statements for the time being," Zhang Zhaohua said: "But I think the explanation of Gewu Zhizhi is correct!"

"Then don't you listen to other people's different opinions?" Gao Chi laughed.

"Listen, listen," Zhang Zhaohua said, "What did Sima Guang and Lu Jiuyuan say?"

"Sima Guang felt that the word 'Ge' means to resist and defend," Gao Chi said: "In other words, he felt that Gewu Zhizhi was to resist the temptation of external objects, and then knew that virtue was the way." ”

"Oh," Zhang Zhaohua suddenly felt that such a statement seemed to make sense: "It is to put aside the influence of external objects in the environment and pursue his avenue." ”

"Then how did Lu Jiuyuan explain it?" asked Zhang Zhaohua.

"Lu Jiuyuan has a very interesting saying," Gao Chi said: "He said, the universe is your heart, and your heart is the unchanging universe heaven and earth." People have the same mind, and the heart is filled with the same truth, this truth is the principle of heaven, man, and physics, so everything is completely contained in your heart, and there is no need for external objects to teach you, what you have to do in this life is to explore your own heart, because your heart is blinded by external objects. So you have to be, all the time, try to get rid of this external object that blinds you, and this is the object, and what you will eventually get is your original mind. Because this heart has long contained all the truths, so when you get rid of external objects, you will naturally see nature in your heart. ”
