The Shunzhi Emperor ascended the throne at a very young age, but because he was young at the time, the real power of the Qing government was always in the hands of the regent Dolgun. It was not until after Dorgon fell off his horse while hunting and died that he began to be called the ruler of the Qing Dynasty in the true sense of the word.

So, is Dorgon's death really that simple? In fact, it is not, and many details reveal that Dorgon's death is actually hidden.
The hero on horseback died because he fell off his horse, which was a joke
The Qing Dynasty was originally founded by the Manchus, a nation on horseback, and Dorgon was the best of the people on horseback. Since childhood, he has learned equestrian skills and has experienced hundreds of battles.
The relevant texts of the Qing Dynasty explain the reason for Dorgon's death in this way, which basically means that Dorgon was not in a good mood because he was unwell, so he took each Belle and the officers and soldiers to go hunting. This was the result of accidentally falling off his horse while hunting, causing him to be seriously injured and died at the age of thirty-nine.
I believe that this reason is believed by anyone, a military general, because of his physical discomfort, so choose to go hunting and relax, this is very normal. However, if you think about it, since Dorgon chose to go hunting on horseback, the illness he received would certainly not be difficult to cure, otherwise he would not be able to ride a horse, let alone hunt. The Qing Dynasty literature does not describe too much about what disease Dorgon was suffering from, but we can infer from normal logic that Dorgon was not seriously ill at that time.
Then, dorgon fell off his horse during the hunting on horseback is even more untrustworthy, ancient warriors, daily equestrian practice, practice archery, not to mention the Qing Dynasty was originally established by the people on horseback. Don't say that the fierce general Dorgon is an ordinary soldier, not fighting with the enemy, not fighting on the battlefield, but falling off his horse in a hunting game used as entertainment and leisure, and causing serious injuries, the probability of which can be imagined.
Moreover, the hunting places were generally in the inaccessible alpine forests, and the warrior-born Dorgon controlled the government and the opposition, and when the emperor gradually grew up, he did not have the protection of the guards in his entertainment and leisure activities, and fell off his horse in the depths of the Maolin Forest, surrounded by some kings who he had never guarded against. Isn't that possible?
Two: The uncertain prophet of the Shunzhi Emperor, thoughtful arrangements
The death of Dorgon is already full of doubts, and the follow-up performance of the Shunzhi Emperor is even more abnormal. Qing dynasty historians recorded the scene of Dolgun's "coffin cart" being transported to the capital.
The Shunzhi Emperor led the Hundred Officials of Wenwu and the Kings of Belle to greet each other five miles away from Dongzhimen. From the Shunzhi Emperor weeping bitterly, down to the officials below the four pins, all knelt and wept by the side of the road.
The number of ceremonies can be said to be quite thoughtful, as the special status of the regent Dorgon, it is normal to have such treatment, but after this, the Shunzhi Emperor immediately issued an order to take all the letters in the regent's palace, collect them in the inner treasury, and seal his reward book.
It can be seen that after the death of Dorgon, the Shunzhi Emperor arranged the number of ceremonies extremely thoughtfully and the treatment was extremely generous. But only then, all of Dorgon's political possessions were immediately confiscated.
If it were not for the advance arrangement, I am afraid it would be difficult to make such a perfect arrangement and reaction in a short period of time, not only in terms of insignificant etiquette, but also in terms of insignificant etiquette, giving generous treatment to the deceased, and appeasing the hearts and minds of the people of their forces. He also quickly counted the merits he had received, the actual carriers of the rewards he had received, the correspondence he had exchanged with other princes and nobles, the letters that had taken away all the powers of representation, and so on. All this shows that this is not an accidental emergency, and it is very likely that it was prepared.
So, if the black hand behind all this is the shunzhi emperor who has the greatest benefits, and then he has the real power of the entire Qing Dynasty, what is his motivation? It is conceivable that part of it must be because of dissatisfaction with the regent Dorgon's continued control of the government and the opposition, and he is not willing to continue to be a puppet emperor, while on the other hand, it is very likely that the Shunzhi Emperor at that time has reached the time when he has to do so.
Three: The cattiness of Brother Dolgun's rebellion
After Dorgon was buried, the Shunzhi Emperor launched a major operation in addition to the merits of Dorgon and the external inventory of letters.
Immediately after this, the Shunzhi Emperor began an inventory of Azig, the brother of one of Dorgon's compatriots, and finally Azig was found guilty.
The Reason for Azig's guilt described in Qing Dynasty literature is that Azig colluded with others in dorgon's funeral and intended to rebel. That is to say, after the death of Dorgon, Azig immediately prepared to launch an armed rebellion, but the matter was revealed.
According to historical records, Azig did bring three hundred soldiers to the capital to prepare for rebellion, but the Shunzhi Emperor had already taken precautions, and had already arranged everything before Azig returned to the capital, and directly imprisoned him on the day that Azig was preparing to rebel, and successfully took over the power, leaping from a puppet emperor to a real Qing ruler with real power.
The warlord Dorgon fell off his horse and died, and Dorgon's brother rebelled in armed rebellion, but was directly convicted and imprisoned by the Shunzhi Emperor.
If you look at it as a whole, you can imagine the logic behind the scenes, is it really only Azig who plotted rebellion? Is there no suspicion that Dorgon, who has a heavy army and controls the government of the dynasty, has no suspicion?
After the Shunzhi Emperor became an adult, his brother Dorgon died suddenly, for reasons so funny that he could not believe it, and his brother was convicted of rebellion. When these are linked, there is only one possibility. That is, the Shunzhi Emperor had long expected that Dorgon and his brother were plotting rebellion. Therefore, there is a good explanation for the sudden death of Dorgon, the revelation of Azig, and the confiscation of Dorgon's correspondence by the Shunzhi Emperor.
