As the saying goes, a companion is like a tiger. During the feudal dynasty, there was a set of procedures, but the emperor could go beyond all procedures at any time and convict himself. This is called a "prison summons".
You let me die and I want you to die. It's just a matter of words, especially in ancient times. Their duty is to give advice to the emperor, who is wise. If you meet a bad king, it is the rhythm of dying hundreds of times a minute.
And salt smuggling. You know, in ancient times, the right to coin, sell salt, cast iron and so on. Be firmly controlled by the government. These are the economic lifeline of the country and an important source of finance, but there are still many people who are not afraid of death to take risks and challenge the majesty of the royal family. After all, this is a high-yield channel, just like drug trafficking now.
Once these people are caught, they will either go to prison and be expelled from the army, or their heads will fall directly to the ground. At that time, Zhu Yuanzhang, the Ming emperor, executed his own clique Xu for selling illicit salt, which caused a sensation at that time.
In fact, there is another occupation that I think is the most "dangerous", but it is also what ancient people want to be.
That's the emperor. In ancient times, how many people did whatever it took to get this coveted throne, how many brothers and sisters killed each other in order to claim the world, the change of Xuanwu Gate and the battle of the prince, and which loser was not ruined and ended up in a miserable end.
Peace and prosperity are good. Once the power falls, my strength declines, and the dynasty is in turmoil, I will be vividly portrayed by others, at the mercy of others, and live a life of larger foe. Think of Emperor Xian of Han Dynasty and the late Tang Dynasty.
When you are a wise monarch, the weather is good and the people live and work in peace and contentment. If you are a tyrant or a bad monarch, people's grievances are boiling, people are displaced, the world is in chaos, and peasant uprisings are one after another. The deposed emperor is not a victim of regime change. Qin Ershi and Emperor Yang Di are good examples.
