The book is picked up again.

In logical mathematics, there is a 'necessary non-sufficient condition': if it is assumed that conclusion B can be deduced from condition A, but condition A cannot be deduced from conclusion B, then condition A is a necessary non-sufficient condition for conclusion B.

To put it simply, there will always be a weeping chicken in a place where there has been a military disaster, but the appearance of a weeping chicken does not mean that there will be a military disaster here.

Treating the necessary and non-sufficient conditions as sufficient and necessary conditions (two-way pushable) is the most common mistake for beginners, and many people have fallen into this pit, especially those who read and read well.

Want to know why? Let me give you an example, "Historical Records. Chen Shi Family".

According to the records in the text, after Chen Sheng and Wu Guang took the incident, they first captured Daze Township, then Qi County, and then Xuan County, Yu County, Ku County, Zhe County, and Qian County.

By the time the rebel army reached Chen County, there were already six or seven hundred chariots, 1,000 cavalry, and tens of thousands of soldiers.

(Attack Daze Township, collect and attack Qi.) Qi Xia, it is the order to leave the people Ge Ying to the east of the army. Attack, drunkenness, suffering, Zhe, and slander are all under it. The line collected troops, compared to Chen, six or seven hundred cars, more than 1,000 horses, and tens of thousands of deaths. Attacking Chen, Chen Shou ordered that he was not there, and he was alone in the middle of the battle gate. Fu Sheng, Shou Cheng died, but into Chen. ）

Looks pretty normal, doesn't it? Now I will mark the current name of the above ancient place name, can you read it again?

Daze Township (about 20 kilometers southeast of present-day Suzhou City, Anhui Province);

Qi County (now Qi County Town, Yongqiao District, Suzhou City, Anhui Province);

Xuanxian County (now seventy miles southwest of Suixi County, Anhui Province);

Yuxian (now Yucheng Town, Yongcheng City, Henan Province);

Kuxian County (now Luyi County, Henan Province, abandoned by war in the Qin Dynasty and rebuilt in the early Han Dynasty);

Zhexian (north of present-day Zhecheng, Henan);

Qiaoxian (now Bozhou, Anhui);

Chen County (now Huaiyang, Henan);

Now you see the problem, right?

At first, Chen Sheng and Wu Guang raised the banner against Qin in Daze Township in the southeast of Suzhou City, then captured Qi County, which was more than 10 kilometers away in the northwest, and then continued to go north 50 kilometers to capture Suixi County (Xuanxian County) in Anhui Province.

After that, the uprising route was chaotic, first killing Yongcheng City in Henan Province, 30 kilometers away due west, then continuing to Luyi County 100 kilometers west, then 50 kilometers northwest to Zhecheng, Henan, then turning 80 kilometers southeast, killing back to Anhui from Henan, and finally the whole army was collectively transmitted to Huaiyang, Henan Province, 150 kilometers east due east.

Say a word about headless flies, and they all hold up this colorful picture.

Obviously, the route given by Sima Qian in the historical records was wrong, not only was there a lack of many key landmarks, but the order of the attack sites was also out of order, and even the rebel army even fought a bitter county that did not exist at all.

During the Qin Dynasty, Ku County had been abolished because of the large number of residents fleeing; It was only after Emperor Wen of the Western Han Dynasty ascended the throne that the people were relocated from other places to recover.

When Chen Sheng and Wu Guang rebelled, there were neither cities nor inhabitants here, and it was impossible for the rebel army to attack here!

In addition, when the rebel army attacked Chen County, the county commander was not in the city, and only one Shoucheng (equivalent to the police chief) and the rebel army fought in the city gate cave.

After Shoucheng was killed, Chen County fell.

I remember when I was in school, I was shocked when I saw this sentence: 'Shoucheng and Zhan Cheng', who gave this Shoucheng the courage to fight with the rebel army in the city gate in front of tens of thousands of foot soldiers and thousands of cavalry? Liang Jingru?

So the real situation should be that the incident of 'Shoucheng and Zhan Qiaomen' did not take place in Chen County, but in Qian County, 150 kilometers away!

This gate is the gate of the county! Shoucheng is the Shoucheng of Qian County!

Qian County is the county seat that the rebel army attacked after Xuan County, and after the repeated battles, the rebel army was seriously short of weapons and supplies and had low morale, so it was regarded as a group of begging people called Huazi by the guards of Qian County......

Therefore, Shoucheng did not go to fight with the rebel army at all, he set up an official stand at the gate of the city to expel the rebel army, and he was not allowed to enter the city and get out of the city quickly.

Then Shoucheng was beaten to death by Chen Sheng and Wu Guangyi at the gate of the city, which is really a sad story.

Speaking of which, a reader asked: "I admit that your research is more detailed, but what is the relationship between Chen Sheng and Wu Guang's incident and the drooping chicken?" ”

Of course it does.

According to the records in the historical records, after Chen Sheng and Wu Guang killed Shoucheng, they ordered the three elders and heroes in the city to come to help the rebel army, and these people gave the rebel army a large amount of military weapons, weapons and food supplies.

After the Battle of Qiaoxian, the rebel army finally looked like an army and began to fight all over Henan in Anhui Province, snowballing in strength.

If someone investigates Chen Sheng and Wu Guang's uprising at this time, once this person ends the investigation after a shallow taste, most of them will come to the conclusion that Chen Sheng and Wu Guang started an incident in Qian County...... After all, before this, the rebel army was like a beggar and an outcast, and it was not a professional history book that would not record it.

Now you understand what I mean?

If Kyobo wanted to find the monster beast he had imagined that could cause the sword and soldier calamity, he would try his best to investigate what strange birds and beasts were in the places where peasant uprisings had broken out.

But the question is, where is the specific location of the Jingfang investigation?

There is no doubt that it must not be Daze Township, but Qian County, which is hundreds of miles away!

Because Jingfang was not a historian, he was not in a position to verify whether the riot in Daze Township was a peasant uprising symbolizing the scourge of sword soldiers, or a riot of displaced people caused by the government's demand for taxes.

But the battle that took place in Qian County must have been a peasant uprising!

Because Chen Sheng began to call himself the king of Chen after this, while fighting everywhere to expand the territory, while dividing the officials to manage the place.

If this is not the standard scourge of swordsmen, then there really aren't many swordsmen!

There is no relationship between whether there is a drooping chicken in Qian County, and whether Chen Sheng and Wu Guang will revolt in Daze Township!

Therefore, it was Jingfang who found the wrong place and came to the wrong conclusion!

And this erroneous conclusion led all the Yi Demon Warlocks after Jingfang to a wrong path.

Originally, the article wrote that it was over here, but the tiger-headed operation officer was stunned and held on to a question: "You say, why is there a drooping chicken in this county?" ”

This is obviously a special case born by chance in a large number of samples.

After all, Qiaoxian is a wealthy county with tens of thousands of households, coupled with the habit of raising chickens in the ancients, with such a large number of sample groups, even if there is a small probability of one in a million, more than a dozen can be found, let alone a drooping chicken?

One more thing, the hometown of Cao Cao, the traitor in the late Han Dynasty, is Qian County, which is really a rich man...... In order to resist Dong Zhuo, Cao Cao scattered his furniture to recruit troops and horses in Qian County, and gathered 30,000 soldiers and horses in just a few months.

In contrast, Liu Xuande recruited troops in Youzhou, and also scattered Zhang Fei's family assets, but only recruited 500 villagers...... Hey, it's all tears.
