Chapter 90 Second Lesson

   Breakfast after morning exercise, go back to sleep after breakfast.

   This has become Xu Guangling's "normal" routine recently, although it is very abnormal.

But there is no way, the morning exercise can only be in the morning, it is impossible to arrange it at noon or something. It can be considered in the evening or at night, but it is staggered with the two old gentlemen, so it is still not considered, and after the morning exercise Being drowsy and sleeping, Xu Guangling couldn't help it, so he could only follow it.

   Therefore, knowing that it is abnormal, Xu Guangling can only be like this.

  For the time being, Xu Guangling has nothing necessary to do during the day. Going to the market to buy vegetables is one of them, but going to the supermarket at night can also be done, and it is naturally not a problem. Other than that, the library has not been there for a long time.

However, the current situation is that even if he is free, Xu Guangling may not go there too much. In the past, reading books was purely an escape, but now there is no need to "borrow books and forget the world", and naturally there is no need to hide in the same way as before. In the book, it doesn't matter if it's dark or white.

   Today, before going to bed, Xu Guangling still set the alarm clock, and it was still set at 6 o'clock in the evening.

   But today, he woke up at 5:30!

This is a welcome change. Although it is only half an hour earlier than yesterday, and I don't know if it will be later at 6 o'clock tomorrow, there is a possibility after all, that is what his body needs after the morning exercise. Rest time is starting to get shorter!

   Or, are you slowly getting used to it?

  If he can wake up like this at noon or at two or three o'clock in the afternoon, Xu Guangling can really be extremely satisfied.

Today is half an hour longer than yesterday, and Xu Guangling took advantage of this half an hour to practice the four moves again, and after experiencing or immersing in the feeling of qi and blood flowing in the body again, it was like yesterday. , set off for Zhang's hometown.

   Today, there is indeed no such thing as two old men, and it is also the door that Xu Guangling took out his own key to open.

The door opened, but the two old gentlemen were sitting in the hall, looking at him and smiling.

   "Humble words come, come, let's go to the study." Zhang Lao stood up first, greeted him like this, and then slowly moved to the study. Xu Guangling closed the door, followed behind Mr. Chen, and entered the study.

   After a while, the three of them sat still as they did yesterday.

   "Humble words, have you ever had a cold before?" Zhang Lao asked.

   Xu Guangling was stunned for a moment, and then said: "Yes, I have had a cold in winter for several years."

   "Then you don't have to worry about it this year. With your current physical condition, normally speaking, it is impossible for you to catch a cold." Zhang Lao said, "Humble words, do you know anything about colds?"

  Xu Guangling really has caught a cold on Baidu! When he had a cold before, he didn't want to go to the hospital, and he was too lazy to go. He checked the cold on the Internet, and thought of buying some medicine at the pharmacy.

   And when he looked further, Xu Guangling was embarrassed or depressed.

  Because he read it for a long time and flipped through the web pages of many sources, he still couldn't figure out which of the two colds he was suffering from. What are the characteristics of wind-heat and common cold? He has! What are the characteristics of cold and flu? He has it too!

  Look up on the wind, heat and cold, how to look like.

   leaned towards the wind and cold, hey, don't say it, it's quite similar!

   When he saw another post saying that he had cold and heat and something, Xu Guangling was immediately angry.

   It doesn't matter whether you have wind-cold or wind-heat, or both, if you like it, I don't care about you! So he didn't even bother to buy some medicine to eat, just relying on the only knowledge he knew, "drink more water when you have a cold", and then let it go.

  After a week, the cold is gone.

  Since then, there are still occasional colds in winter, but Xu Guangling never thought about taking medicine or anything, and has always dealt with it by drinking plain water.

   Besides, why do you have a cold? What is the cause of a cold?

   Baidu's answer is bacterial or viral infection. But when I made a further understanding, the embarrassment of deja vu happened again! That is, Xu Guangling watched it for a long time, but he didn't understand what the difference between bacterial or viral infection was to people!

   At this time, it can be considered that he has found the person who "complained". Xu Guangling poured out his search and depression at that time.

   After hearing what he said, the two old men in the study were all laughing.

After laughing, Zhang Lao shook his head slightly, not knowing what he was expressing noncommittal about, and then he stopped the topic and said to Xu Guangling like this: "Humble words, are you familiar with ancient Chinese history? About the interaction between the Central Plains and the nomadic peoples. ?"

   Listening to Zhang Lao's question, Xu Guangling had a little understanding in his heart, and then said: "I'm not very familiar, but I understand a little bit."

At the beginning of the topic, it must have started from Qin Shi Huang, the first emperor of the generation who was revered as the "ancestral dragon", who dispatched the people of the seven or six countries, and may also be limited to the strong people, built the Great Wall, and opened the door to defend against the enemy (nomads) The first step outside.

   But in fact, with the national strength of Da Qin at that time, there was no need to build the Great Wall.

   Nomads?

   Play as much as you want!

  No, it should be said that the nomads at that time should have fled in the wind in the hope of Daqin. And if it is for the sake of future generations, then there is no need to mobilize the people to build the Great Wall on a large scale, and it is completely possible to slow down.

   Therefore, there is also a saying that the construction of the Great Wall is not actually to defend against the enemy, at least this is not the main reason, and it is more likely to be an incidental, indispensable. The real reason for the construction of the Great Wall was "to consume the six countries' strong men, so that there will be no repeats."

   Simply put, this is the removal of the greatest internal instability in order to establish a truly grand unified empire.

   is a major national policy of "focus on the present, look to the future" and "ruthless means and clever strategy".

   Of course, Xu Guangling has no in-depth understanding of this, and no directional research, so he is just copying what others say.

After Qin came the Han Dynasty. The Han Dynasty was not as powerful as the Qin Dynasty, and it was also the first example of "harmony". The extremely famous "Zhaojun out of the fortress" in history happened during this period. Xu Guangling also appeared in the Northland tour before. Yu Qi specially went to visit the tomb of Wang Zhaojun, the so-called "Qing Tomb", but there was nothing to see.

   Looking at the entire Han Dynasty, the Central Plains still took the initiative. Once the weak period at the beginning of the founding of the country was passed, the nomads were no opponents at all.

After   Han came the Three Kingdoms.

After the Three Kingdoms, it was the "Five Husbands" of "the first decline of the Central Plains", and then the land of the Central Plains entered a long chaotic situation of "Qin loses its deer, and the whole world chases it away", the Eastern Wu, Eastern Jin, Song, Qi , Liang, Chen, the so-called "six dynasties", that is, occurred in this period.

  Although Xu Guangling knew a lot about the Chinese history of this period because of his father, he was still a mess.

   Because of that period, it was really messy! Those who do not specialize in the study of history have no idea at all about the change of regimes in the past two or three hundred years, like a revolving lantern, "the city head changes the king's flag", this sentence is not false at all.

   Then there is the sentence in the Romance of the Three Kingdoms, long-term unity must be divided, long-term separation must be united.

   The Sui Dynasty, like the previous Qin Dynasty, gathered the Central Plains again to complete the initial unification.

However, its fate is also very similar to that of the Qin Dynasty at a certain point. That is, the death of the second generation is actually the **** of the next dynasty and the predecessor of the king. "Luohong is not a ruthless thing, it turns into spring mud and replaces flowers." - Of course , they certainly do not have such a noble sentiment as "more protection of flowers".

   After the Sui Dynasty came the Tang Dynasty. After the Tang Dynasty, the Central Plains section was broken again, and it was broken into the Five Dynasties and Ten Kingdoms.

   Then Song folded again.

After the Song Dynasty, it was broken again, and this time, it was no longer "the country broke the mountains and rivers", but the country broke, and the mountains and rivers also fell into the hands of nomads. This is the first time that the Central Plains of China has truly changed hands. Then from Yuan to Ming, from Ming to Qing, and then from Qing to modern.

   These thousands of years of history are simply fighting the landlords.

  For cattle and horses, either the south wind prevails over the north wind, or the north wind prevails over the south wind. Everyone takes turns sitting in the village, sitting in rows and eating fruit. ——Of course, the real history is far from being so easy, but accompanied by the deep sigh of "I would rather be a dog of peace than a person in troubled world", and there is so much tragic and tragic in the meantime, needless to say.

  Xu Guangling replied to Zhang Lao with a simple understanding of such a situation.

  ==

  Thanks for the support of the recommendation ticket of "Let me be free from the common things of the world".
