One: the right to assemble troops.
Just like Zhao Kuangyin in Song Dynasty, a glass of wine freed soldiers. The Qin dynasty must concentrate all the forces in the world in the hands of the emperor and remove the relieving power of most military commanders. The same was true in the Sui Dynasty, which focused on preventing Yang's distant relatives Li and Yu Wen, taking all their heavy troops back to the central authorities and sending people to closely monitor them.
Two: tax reduction and corvee.
After the Qin dynasty unified the world, it did not give the people of the world a chance to breathe, and continued to recruit talents. First, Epang Palace was built for the first emperor, but the project is not over yet. Then, because of the invasion of barbarians in the north, civilian workers were sent to build the Great Wall. It made the people miserable, and then the peasants rebelled. It turned out that the six countries rebelled one after another.
The Sui Dynasty was established after the Qin Dynasty, but it did not learn the lessons of the Qin Dynasty. Just pacified the world and unified the north and south regions, and then dug the Grand Canal. I didn't think it wouldn't matter if I didn't dig. Once I dig, I will be proud. The Grand Canal painstakingly dug in the Sui Dynasty was given to the Tang Dynasty as a dowry.
Three: reduce the punishment and grant Amnesty to the world.
Qin was harsh because of Shang Yang's political reform and was always beheaded. At first, the local people of Qin adapted to this law and performed well, but with the movement of Qin Jun, this law was extended to other six countries. According to the laws of other countries, what you do when you apologize is beheaded according to the laws of Qin. How can this stand? They must be thinking, the Qin dynasty made it clear that horses should run and not eat grass. This is unbearable. Let's start the uprising. So, Chen Sheng rebelled, and then the butterfly effect, the Qin Dynasty was not good.
If the Qin and Sui Dynasties adopted the practice of letting the people recuperate as in the early Han Dynasty, then the people behind them might not be so riddled with moths. After all, who doesn't want to live a quiet life? After playing for so many years, the people are tired. Give them some steps.
Four: Determine a good successor and a suitable coaching team.
In the Qin Dynasty, there was an excellent Chu Jun Fu Su who didn't use it. He had to be sent to the frontier to keep the peace. In this way, the center of power is only the treacherous court official headed by Zhao Gao and the useless Hu Hai. As a result, when Ying Zheng died, the world fell to Hu Hai and Zhao.
When the Qin dynasty met these two talents, it was either death or death.
In the Sui Dynasty, because someone was inspecting Yang Di, the result was different from the official history, so I didn't comment.
Therefore, if you don't want to be cut off, you have to be similar to those dynasties that can exist for a long time. In other words, once a suitable successor is determined, it is necessary to prevent dangerous ministers, let the people rest, reduce punishment and reduce taxes.
