Chapter 92 After School Tea Time

Zhang Lao didn't say much about the specific food he was angry with. He almost asked Xu Guangling to temporarily understand the term, and then today's lecture, um, seriously speaking, it is a lecture, casually speaking, it is nagging, even if it is an end. .

   Today, Zhang Lao just popularized the knowledge of colds for him, and then also tested his understanding of Chinese history, haha.

  Xu Guangling has decided to take "Chinese History" as an elective course for a period of time in the future. It's not that he wants to be fond of Zhang Lao, but Xu Guangling feels that if he keeps coming here to listen to Zhang Lao like this, he may need historical knowledge.

   Let’s take today.

   If he hadn't understood the interaction between the ancient Central Plains and the northern nomads, Zhang Lao's explanation would certainly not be like this. - What would that be like?

   Xu Guangling doesn't know, but one thing is certain, that is, it is definitely not as good as it is now.

   His performance cannot be said to make Zhang Lao very satisfied, but generally speaking, he should still be qualified.

   But "qualified" has never been Xu Guangling's requirement. As I said before, not only "qualified" is not, not even "excellent", but "perfect" or close to perfection. But Xu Guangling was not too demanding of himself, just like today's matter, it is acceptable to pass.

   After all, it was quite a good thing that he had these knowledge reserves when the incident happened suddenly.

   But today is today, and the future is in the future. If he still maintains a qualified level in the future, it must be something that Xu Guangling cannot accept. Therefore, according to the needs of Zhang Lao, timely corresponding additional supplementary lessons must be put on the agenda.

   After the lecture, when Zhang Lao went to make tea again today, Xu Guangling followed him, and then took over Zhang Lao's work in a timely manner. Zhang Lao did not stop him, hehe smiled and let him come.

   did not enter the study room again, the three of them just sipped tea in the living room as a rest.

During this leisure time, Xu Guangling remembered how he felt when he practiced the four moves and one form today, and asked Mr. Xiang Chen: "Old Chen, when I practiced the form you taught me yesterday, my body felt a little bit weaker. The feeling is particularly obvious, is there anything I need to pay attention to?"

  Xu Guangling said, and then described his practice experience in more detail. Of course, the most important thing was that he seemed to clearly feel the flow of Qi and blood in his body.

Xu Guangling asked Mr. Chen, because Mr. Chen taught him, but after listening to what he said, it was Mr. Zhang who said: "Humble words, I will answer this question for you, you first Go outside and get a leaf and come back."

  Xu Guangling was slightly surprised, but immediately got up and complied.

After Xu Guangling went out, to be precise, when he turned his back to the two old men and walked out of the small building, in the living room, the two old gentlemen looked at each other with deep expressions in their eyes. The expression of shock, and even Mr. Chen, who is a "master of the first generation", has obvious envy in his expression. As for Mr. Zhang, let alone Mr. Zhang.

   Then, Mr. Chen smiled wryly, while Zhang was helpless.

   The next moment, the two old gentlemen turned their heads in unison, followed Xu Guangling's figure with their eyes, watched him walk out a little bit, and watched him step by step.

   Being watched by the two old men and walking into the living room, Xu Guangling felt a little uncomfortable, but he didn't think too much for a while, "Elder Zhang, do you think these leaves are suitable?"

   Zhang always asked him to take a leaf back, because he didn't know Zhang Lao's intention, so Xu Guangling simply took three leaves, one green, one withered yellow, and one half green and half withered. At this time, seeing his little ingenuity, the two old people suddenly felt a sense of humor, Zhang Laoqing couldn't help shaking his head slightly, and said with a smile: "Okay, this one will do."

   He reached out and took the half-green half-withered one from the three leaves.

   After Xu Guangling sat down, Zhang Lao said slowly: "In my humble opinion, living things are divided into three categories: microorganisms, plants, and animals. You should know that."

   Xu Guangling didn't know much about biology, but he really knew this. - If he didn't even know this or said he had forgotten it, all the biology teachers in his junior high and high school would have tried desperately to find him if they knew about this situation.

Seeing Xu Guangling nodding, Zhang Lao continued: "Let's not mention microorganisms. Plants and animals seem to be completely different, but in fact they have a lot in common. In nature, there are also many creatures that have both characteristics at the same time. ."

   At this time, Zhang Lao did not give an example, and it is estimated that even if he gave an example, Xu Guangling might not know much.

But Xu Guangling still nodded at this time, expressing his understanding, and took the initiative to show Zhang Lao two examples to show that he really understood: "Zhang Lao, piranha, Venus flytrap, it should be what you said. Such creatures?"

   Hearing him say that, Zhang Lao smiled and nodded, then said:

   "Plants and animals are just an expedient division made by the scientific community in order to make a better distinction between organisms. Note that it is expedient, so seriously, it is not rigorous."

"Just as now we call a vegetable that can be eaten raw 'lettuce', and it is only expediently. Because if there are many vegetables that can be eaten raw in the future, and this is inevitable, what will happen then? What's the name? You can't call it 'Lettuce No. 1' and 'Lettuce No. 2', and keep going down the row like this, right?"

   Xu Guangling laughed.

"Humble words, I say this to tell you that the difference between plants and animals is not as big as most people think, nor are they two completely different types. Essentially, they have more in common. This means that What? Means what happens to plants can sometimes be applied to animals, and vice versa."

   "There was news before that a tree was sick, and people gave it a 'hanging needle', and the result was really cured by this method. Have you heard of this news?" Zhang Lao asked.

   Xu Guangling had really seen such news on the Internet, and it seemed that there was more than one case, so he nodded when he heard what Zhang Lao asked.

"Okay, then we can start your question now." Zhang Lao said, and then he shook the leaf that he just took in his hand, "Humble words, look at this leaf, these things on it. Context, if people are used as a comparison, what should they correspond to in the human body?"

   This is simply asking Xu Guangling as a kindergarten friend!

Xu Guangling smiled bitterly, but he still didn't dare to answer too affirmatively. It doesn't matter if he was slapped in the face. The key is to "know what you know, and don't know what you don't know." , but he still used a questioning tone at this time: "Vascular?"
