Jiujiu and Lao Qin fought against the national calamity together.
After the death of Fen VI, Qin Shihuang unified the Warring States and established the first feudal dynasty in Chinese history. But the First Emperor probably never expected that the country he had worked so hard to build would end in just fifteen years.
Everyone regards Hu Hai, Zhao Gao and others as the main reasons for Qin's demise. However, the three unreasonable aspects of the Qin Dynasty's demise are often easily overlooked.
First, Chen Sheng’s development is too rapid. Secondly, the Lishan prisoners were too good at fighting, and thirdly, how could Liu Bang conquer Xianyang so easily?
Behind these unreasonable things may be the real reason for the demise of Qin.

The world is in chaos
It will rain heavily, the road is blocked, and the time has expired. If the deadline is missed, all laws will be cut off. The origin of all the stories of
begins with a heavy rain. When facing a certain death situation, Chen Sheng and Wu Guang chose to lead an uprising. This was also the first large-scale peasant uprising in Chinese history.
Let’s not talk about their revolutionary initiative, which inspired millions of working people in later generations to resist brutal rule. It is incredible that the two of them alone were able to raise an army of more than 100,000 people in just a few months.

Where did Chen Sheng find so many troops? Why does he have such strong appeal?
As for the prisoners of Lishan whose fighting power was too fierce, the prisoners of Lishan led by Qin general Zhang Han actually defeated the uprising troops from all over the world.
Chen Sheng and Wu Guang's hundreds of thousands of troops seemed to be huge in number, but they were destroyed in a very short period of time. Not only that, even when facing Xiang Liang, a descendant of the Chu nobles, Zhang Han showed extremely strong performance.
Even after Xiang Yu annihilated Wang Li's entire army in the Battle of Julu in the early stage, Zhang Han relied on the Lishan prisoner army in his hands to persist for eight months . This is why.

You must know that no famous general in the world can "temporarily" train a group of prisoners to be soldiers who can rush to the front line to kill the enemy bravely.
Even the soldiers recruited normally have to go through the baptism of war again and again before they can grow up. Considering Zhang Han's ability, this is really a bit reluctant.
In addition, Zhang Han and Xiang Yu fought extremely fiercely, and Liu Bang took the opportunity to lead troops from Wuguan into Xianyang. How dare he?
Descendants have a God's perspective and naturally know that the city defenses around Xianyang are empty. But as Liu Bang was a man in the game, it was impossible that he had not heard of the name of the Xianyang garrison.

This army was first established in 306 BC . "Yunmeng Qin Slips" records that the treatment standard of each soldier in the army is at least twice higher than that of ordinary soldiers. Its combat effectiveness is astonishing, and it is known as one of the eight elite troops in ancient China.
This is not to underestimate Liu Bang, but judging from his armed strength at the time, did he really have the guts to compete with such a powerful force?
Liu Bang not only "won", he also became the first rebel leader to take control of Xianyang.

Death of Qin
In fact, if you compare the entire process of the demise of the Qin Dynasty together, you will find that. Liu Bang may have guessed the true identity of the Lishan prisoners under Zhang Han when he attacked Xianyang.
They are not prisoners, but the Xianyang garrison who fight against all the rebel armies in the world in the name of prisoners. If it were not for facing such a strong opponent as Xiang Yu, even if the uprising at the end of Qin could succeed, there is no telling how long it would have dragged on.
Because of this, when Chen Sheng and Wu Guang launched an uprising, Zhang Han was able to defeat hundreds of thousands of troops with an army of tens of thousands.

Why is it named after Lishan Prisoner? Its purpose is two-fold. First, it is to attract the attention of all the rebels and make the princes mistakenly think that the Xianyang garrison has not yet been mobilized.
The second is to borrow Lishan prisoners, to reduce the losses of the garrison . Yes, a large part of the Lishan prisoner army under Zhang Han is indeed a real prisoner. But the garrison was separated and the prisoners had no way to resist.
Although the answers to the last two questions have been found, why Chen Sheng was able to raise hundreds of thousands of troops in a short period of time was the most fundamental reason for the demise of the Qin Dynasty.

After Qin Shihuang unified the six countries, he managed the country through the county system. But the so-called counties and counties at that time actually arranged for Qin officials to serve as officials in the territories of the princes and states in the world.
The advantage of doing this is that the Qin State can understand the trends of the world at any time, but the actual disadvantage visible to the naked eye is that the officials are in name only and cannot completely control the place.
Especially when countries such as Qi, Chu, Yan, Zhao, Wei, and Han perished not long ago, everyone was thinking about the original country. A Qin person managed it according to Qin law, and the deep resentment of the people was evident.

When Qin Shihuang was alive, he took advantage of the power of unifying the six countries, and no one dared to say a word "no". This was not only his personal "power", but also the "power" of Qin.
As soon as the First Emperor died, this momentum gradually dissipated until it disappeared without a trace. As long as someone leads the rebellion, the people who do not support Qin's governance will naturally be willing to support and respond.
Why Chen Sheng was able to mobilize so many troops was not due to his personal charisma or the influence of the so-called " Great Chu Xing, King Chen Sheng" . It was just that the people wanted to resist, but Chen Sheng just started to do it again.
A single spark ignited a prairie fire and finally burned Epang Palace to the ground.
