Yang Zheng said: "When Weichen was a child, I heard the story of Meng Jiangnu crying on the Great Wall, saying that Qin Shi Huang was heavy in labor for the construction of the Great Wall, and the young men and women Fan Xiliang (Fan Qiliang) and Meng Jiangnu were newly married for three days, and the groom was forced to set out to build the Great Wall, and soon died of hunger, cold and fatigue, and his bones were buried under the Great Wall.

Meng Jiangnu was wearing a winter coat, went through hardships, and came to the Great Wall in search of her husband, but what she got was the bad news of her husband's death. She cried bitterly under the city, ten days and ten nights, this section of the Great Wall collapsed, revealing Fan Xiliang's body, Meng Jiangnu buried Fan Xiliang and then threw herself into the sea in despair and died...... At that time, Weichen was still young, and only felt that this Meng Jiangnu was a poor person, and Qin Shi Huang was a remnant Bao Jun, but then Weichen grew up, recited poetry and books, understood the reason, and then heard people talk about Meng Jiangnu crying on the Great Wall, but it is not difficult to see, Meng Jiangnu's misfortune is certainly worthy of sympathy, and Qin Shi Huang's exploits cannot be erased. ”

It was the first time for everyone on the field to hear such a statement, and they couldn't help but feel a little surprised.

Zhu Zhanji glanced at Yang Zheng and said, "How can you say this?"

After brewing just now, Yang Zheng's head was also a lot more flexible at this time, and he pondered for a moment, and said, "Dare to ask the emperor, why did Qin Shi Huang build the Great Wall?"

"It's for the sake of fighting the Hu people!" Zhu Zhanji said.

The Hu people referred to in the Qin period were the Xiongnu in the future. Tracing back to the historical origins, the Xiongnu were originally a member of the Chinese nation. As far as the Qin state is concerned, its early history of founding can be called a history of struggle against the Hu people, with both failed lessons and successful experiences in between. During the reign of King Zhaoxiang of Qin, the Hu people threatened the northern border of the Qin state, and the Qin state adopted a strategy of fortifying and defending the Hu people out of consideration of eastward advance.

In the middle and late Warring States period, the power of the Hu people was further enhanced, and their erratic way of fighting was a headache for the Central Plains countries. King Wuling of Zhao reformed his armament with Hufu cavalry and archery, and won a great victory in the struggle against the Hu people.

When Qin Shi Huang unified the whole country, the Xiongnu gradually became a relatively unified country from a plate of scattered sand, and their strength increased. The leader of the Xiongnu called "supporting the plough lonely Tu Shan Yu", "supporting the plough lonely Tu" is the meaning of the Son of Heaven, "Shan Yu" is the meaning of the broad, and the Central Plains people used to refer to them as Shan Yu for short.

At that time, the border between the two sides was relatively stable, and there were no large-scale clashes between the Qin army and the Xiongnu. On the one hand, this is because the Qin army is good at fighting, and the Huns do not dare to provoke lightly. On the other hand, it is also because of the sinister shape of the Xiongnu, they are bordered by the Dayue clan in the west, Donghu in the east, and Qin in the south, and there are strong enemies on three sides, and the Xiongnu do not dare to act rashly.

Judging by the situation at that time, if the Qin Empire did not take the initiative to provoke incidents, the Xiongnu would never dare to go south. Qin Shi Huang was a strategic emperor, and he had already had the heart to conquer the Xiongnu. In the twenty-sixth year of the first emperor, that is, the Qin state had just completed the unification, Qin Shi Huang intended to strike while the iron was hot and subdue the Xiongnu in one fell swoop.

He convened a group of ministers above the temple to discuss the matter, which was strongly opposed by Prime Minister Li Si. Li Si believed that fighting with the Xiongnu would have disadvantages but no advantages, and after analyzing the situation on both sides, he gave several reasons not to attack the Xiongnu:

First of all, the Xiongnu had no fixed residence, and it was difficult to subdue them. This is largely due to the fact that they have no city to live in, no wealth to protect, and no fear of attack.

Second, attacking the Xiongnu, Great Qin will be in a dilemma. If the light cavalry is sent to fight a quick battle, it will be difficult to solve the problem of grain and grass supply, and if the heavy troops are sent to press the border, the mobility of the troops will be damaged, and it is likely that they will not be able to pursue the Xiongnu.

Thirdly, even if the Huns were defeated, the result would be unprofitable. The Xiongnu were located in a wilderness, and the economy and culture were very backward, so they did not have much benefit to the development and growth of the Qin State. On the other hand, the captured Xiongnu people are not easy to control, and if they can't get it right, it is still a safety hazard. But if they are killed, it is not something that the common people of the world and His Majesty are willing to see.

Li Si came to the conclusion that the expedition of the labor division to the Xiongnu would only consume the power of the imperial court and had no actual benefits, which was not conducive to the long-term development of the Qin state.

It should be said that Li Si's analysis is quite insightful, and the development of the future shape shì also has many coincidences with his analysis. Li Si was Qin Shi Huang's most relied on minister, and his views carried considerable weight in Qin Shi Huang. In addition, the Central Plains had just been reunified, and everything was in ruins, and it was obviously more appropriate to stabilize the situation in the Central Plains than to rashly attack the north, so Qin Shi Huang had no choice but to put aside his plan to attack the Xiongnu in the north.

But six years later, the threat of the Hu people became bigger and bigger, Qin Shi Huang felt that the empire was often in crisis, after some consideration, regardless of the unstable Central Plains, decided to eliminate the hidden dangers of the Great Qin Empire first, he appointed the general Meng Tian, who could fight well, to lead 300,000 elite soldiers to launch a strong attack on the Xiongnu, and recovered Henan and Yuzhong in one fell swoop, and recovered Gaoque in the second year, reaching the Yinshan and Hetao regions. The Xiongnu were hit hard, not only could they not withstand Meng Tian's attack, but also worried that the east and west flanks would be attacked, and finally fled to the north of the desert.

The Qin army's battle against the Xiongnu should have been a complete victory on the surface, but as Li Si pointed out back then, the Hu people had no fixed place to live, there was no territory that could not be abandoned, and they could move at any time, and the victory of the Qin army did not have much substantive content to speak of, but added a lot of trouble to itself.

The Huns' war of changing places with one shot caused the Qin army to be very troubled, and in order to prevent their intrusion, Qin Shi Huang decided to build the Great Wall. The place of Pingchuan was suitable for the Huns to act on horseback, and it was an effective way to build cities to limit their strengths.

As early as the seventh century B.C., in order to defend against each other's attacks, princes began to build tall walls on their territory, which were called the Great Wall. Before and after the Warring States Period, Yan, Zhao, Qin and other countries also built the Great Wall one after another in order to defend against the raids of the northern nomads.

The construction of the Great Wall to defend against the enemy is an ancient method, which is not a pioneering initiative, but it was exerted by Qin Shi Huang to the extreme, and its impact on later generations is extremely far-reaching. After the Qin Dynasty, there were very few dynasties that did not build the Great Wall.

Qin Shi Huang not only connected the old Great Wall of Zhao, Qin, Yan, Han and other countries into a line, but also added and expanded many parts, forming a 12,000-mile long Great Wall. Qin Shi Huang not only built the Great Wall, but also built straight roads. His idea was that the Great Wall could resist the invasion of the Hu people in the north and ensure that Qin would not be destroyed by the "Hu". The cultivation of the straight road can make the cavalry of the Qin State reach Yinshan within three days and three nights, and deal a fatal blow to the "Hu people".

In today's view, the Great Wall is a great miracle, but in the Qin Dynasty, when the productive forces were not yet developed, the construction of the Great Wall was a complete disaster and catastrophe for the common people, and later generations also regarded this incident as one of the tyrannies of Qin Shi Huang.

There was silence on the field, but Yang Zheng kept talking, paused a little at this time, and continued: "Although Qin Shihuang is not very good, the credit for building the Great Wall can be compared with Dayu's water control. If there was no Great Wall to defend the Central Plains, China might not have been able to wait for the Sui, Tang, Song, Yuan, and Ming dynasties, and would have died in Beidi in the Chu and Han dynasties, let alone the prosperity of the Han and Tang dynasties. Because the existence of the Great Wall has enabled the assimilation of the Chinese nation to be strengthened and consolidated, it is possible to " Although I died in Mongolia, and Mongolia was assimilated by me, and only then did I have the Ming Dynasty, it can be said that China used to build the Great Wall for Qin Shi Huang, so as to protect our advanced culture in the Central Plains, and to protect our nation from foreign invasion, but at that time, a few people would look at it this way, they would think like this, their eyes were only staring at the first emperor to send 300,000 troops, Meng Jiangnu cried and broke a section of the Great Wall, but they didn't think that if Qin Shi Huang had not sent 300,000 troops, how many casualties would the Xiongnu invasion have?"

Yang Zheng's words are speaking from the standpoint of being a human being in two lives, whether it is gaze, Or the mind is not comparable to contemporary people, especially he clearly stated the exploits of Qin Shi Huang to build the Great Wall, which made everyone feel a little surprised, they have been familiar with the Four Books and Five Classics since childhood, Qin Shi Huang built the Great Wall, has always thought that it is one of his tyranny, and that Meng Jiangnu is one of the evidence of Qin Shi Huang's construction of the Great Wall, even some enlightened historians believe that the construction of the Great Wall is the brutal side of Qin Shi Huang, they keenly pointed out that the Qin Empire seems to have solved the northern trouble, but the victory on the battlefield is only temporary, Qin Shi Huang throughout his life, did not fundamentally solve the Xiongnu problem, although the nomads were temporarily shocked but absolutely did not give in, "Qin Exterminator Hu" is the lingering pain in his heart. The defensive role of the Great Wall was also very limited, and the reason why the Han and Tang dynasties flourished was not because of the Great Wall, but because of its open culture and strong national strength.

Didn't the Song Dynasty build the Great Wall, and was not bullied by the Liao, Jin, Xixia, and Mongolia, so the Great Wall has never been able to stop the iron horses of the northern nomads, and they have always believed that building the Great Wall is a way to build the Great Wall since ancient times, and building the Great Wall to resist external attacks is a strange circle, and it has almost reached the Cheng dù of a vicious circle. The greater the effort to build the Great Wall, the stronger the fear of invasion by foreign enemies, the more money and goods the country will expend, and the weaker the combat effectiveness of the troops. There is no year when the country does not spend a lot of money on the construction of the Great Wall, but the efficacy and value of the Great Wall cannot be reflected. The Great Wall has become synonymous with passive defense, and the Great Wall has been built with huge manpower, material and financial resources, because the defense line is too long, and the rigid and negative city wall is difficult to withstand the sudden attack of the enemy. Minyue is the state, and the border is self-consolidated, and the so-called unity is also. Yang Zheng affirmed the Great Wall so much, it was the first time, and he forgot to speak for a while.
