During Shunzhi period, a plague broke out in Beijing. At that time, Dourgen immediately ordered that anyone who had not had smallpox should leave Beijing for 20 kilometers to take refuge. This order went to the people, officials and even the emperor shunzhi to get out of the city to avoid chicken pox.
At that time, an uncle of the emperor shunzhi, Prince Yu, was unfortunately infected with chickenpox. As an uncle, he certainly got the best medical care and service. And at that time, he was still very strong and made a lot of contributions. It was such a general who died of smallpox 10 for more than a few days.
Enough to see how terrible this disease is. Manchu people have never had this disease before, and they don't know what the source of this disease is. All I know is that smallpox has a high mortality rate if it is not treated. 10 people will have three or four deaths.
Even the emperor shunzhi himself later failed to escape smallpox and died of smallpox at the age of 24. It is said that an important reason why Shunzhi chose Kangxi to succeed to the throne at that time was that Kangxi had smallpox when he was a child. People who have had smallpox will not get it again if they have antibodies.
Shunzhi knows how bad it is to change emperors frequently. He didn't want the next emperor to continue to be like him, so he chose Kangxi. At least in the next few decades, smallpox will not kill another emperor.
When Kangxi was a child, smallpox was also an extremely thrilling thing. If his wet nurse didn't take good care of him and took him away from the palace to take care of him, Kangxi might not be able to carry it. Although Kangxi was cured, he left many scars and marks on his face, which is said to be pockmarked face.
