On April 22, the seventeenth year of Chongzhen, Wu Sangui, the Qing army and Li Zicheng's army fought a stone outside Shanhaiguan. Li Zicheng left, and the Qing army took advantage of the situation to pursue.

Fan Wencheng helped the sick with the expedition, and proclaimed: "The volunteers are coming, in order to avenge the monarch and father, not to kill the people, but to punish the thieves." Those who come and return will return to their officials, and those who come and return will return to their jobs. The teacher is strict in discipline, and he will not be harmed. “

His documents are all signed with Fan Wencheng's official rank and surname. Public opinion was then peaceful, and the Qing army quickly implemented it. Li Zicheng abandoned Beijing and fled.

On the second day of the first month of May, the regent Duoerhong entered the Forbidden City under the welcome of the former Ming Dynasty civil and military officials.

This proves from another side that the former fortified city has been devastated by the plague.

At this point, the purpose of the Manchu Qing Dynasty's troops changed from taking advantage of the chaos to seize Beijing gorgeously to "revenge the monarch and father", so the Qing history naturally did not talk about the plague in Beijing.

As for the plague raging in the city of Beijing, it gradually subsided as the weather and temperature rose.

On the second day of the fifth month, it is converted into the solar calendar, which is the solar term of the mango seed. Jiashen year and Gengwu month, that is, the first day of the horse month in the year of the monkey, and the middle day of the horse month is the summer solstice.

If the second day of the fifth month is converted to the Gregorian calendar, it is June 6 in 1644. If we refer to another plague that broke out in Beijing in the spring of 2003 AD, you will find that the plague in Beijing always ends in June.

In 2003, SARS pneumonia broke out in China. SARS first broke out in Guangdong in February and spread to Beijing in March.

On April 1, the U.S. government recalled all non-essential diplomats and their families in Hong Kong and Guangdong. On April 2, China notified all cases to the World Health Organization. Guangdong province reported 361 new cases and nine deaths in March. At the same time, people in Beijing, Shanxi, and Hunan have also been infected. The Ministry of Health said the condition in Guangdong had been largely controlled.

On April 3, the Ministry of Health held a press conference in Beijing. Minister Zhang Wenkang said that the epidemic has been effectively controlled, and he joked that there were only 12 cases and 3 deaths in Beijing at that time, and it was safe to wear a mask or not. The original words are as follows:

"Since the discovery of atypical pneumonia in early 2003, a total of 1,190 cases of atypical pneumonia have been reported in Chinese mainland as of March 31, including 1,153 cases in Guangdong Province, 12 cases in Beijing Municipality and 4 cases in Shanxi Province. In addition, after retrospective investigation, there were 11 cases in Guangxi Zhuang Autonomous Region, 7 cases in Hunan Province, and 3 cases in Sichuan Province. A total of 934 people have been cured and discharged, accounting for 78.5% of the total cases. Among them, 911 cases were in Guangdong, 1 case in Beijing, 8 cases in Guangxi, and all cases in Hunan, Shanxi, and Sichuan were cured and discharged, and no new cases occurred. ”

On the morning of April 6, in order to show that the atypical pneumonia epidemic has been effectively controlled, led by the secretary of the Guangzhou Municipal Party Committee and other key leaders, 20,000 people in Guangzhou Tianhe Sports Center started the Guangzhou Spring Fitness 10,000-person long-distance running activity.

At the same time, Jiang Yanyong, a retired doctor at the 301 Hospital of the People's Liberation Army in Beijing, was sent to the 309 Hospital for consultation at the end of March when he learned that a colleague had lung cancer and symptoms of SARS. Dr. Jiang Yanyong learned from 309 Hospital that there were 40 SARS patients and 6 deaths in 309 Hospital. A day later, it increased to 60 cases and 7 deaths. At the same time, Jiang Yanyong learned that there were also 40 SARS cases in 302 Hospital.

Jiang Yanyong was furious. He believes that Zhang Wenkang's announcement of a seriously reduced figure is misleading to the Chinese people. On April 4, Jiang Yanyong wrote emails to CCTV and Hong Kong's Phoenix Satellite TV to report the situation, but to no avail.

Late at night on April 8, he was found by phone by Susan Jakes, a correspondent for Time magazine in China, and was interviewed.

On April 9, Time Magazine published a report titled "Beijing Attacked by SARS", citing information provided by Jiang Yanyong.

Susan Jakes later revealed to a limited extent that she did not know Jiang Yanyong before. It was a "friend" who forwarded Ms. Jiang's e-mail to her and the reporters of the Wall Street Journal.

On April 10, Vice Minister of Health Ma Xiaowei said at a press conference of the Information Office of the State Council: China's report on the SARS epidemic is credible. The number of cases reported is accurate.

On April 11, a team from the World Health Organization (WHO) began a four-day inspection of the epidemic situation of SARS in Beijing and its prevention and control work.

On April 12, the World Health Organization listed Beijing as an epidemic area.

On April 13, China decided to list SARS as a notifiable infectious disease under the Law of the People's Republic of China on the Prevention and Treatment of Infectious Diseases.

Since then, large-scale public prevention and control has been carried out, and the official figures from now on should be timely and credible.

Analysing the data, it is clear to conclude that, despite the rapid implementation of containment measures, the number of people likely to be infected skyrocketed in April, peaking between April 20 and 26. It can be reasoned that the temperature in Beijing is likely to be the dominant factor.

On April 20, the number of confirmed cases of SARS announced by Beijing increased to 339 from 37 the previous day, and the number of suspected cases increased to more than 600.

On the same day, the government announced that the May Day "Golden Week" would be suspended, and many colleges and universities in Beijing would suspend classes.

On April 23, the Ministry of Finance announced the use of the central government's 2 billion SARS prevention and control fund.

On the same day, Beijing announced that primary and secondary schools in the city would be suspended for two weeks from 24 July.

On April 26, the Ministry of Civil Affairs and the Ministry of Health jointly issued an emergency notice, requiring that the bodies of patients who died of infectious atypical pneumonia should be cremated on the spot in a timely manner, and that farewell ceremonies and other forms of funeral activities should not be used.

In the seventeenth year of Chongzhen, Li Zicheng's team entered the city of Beijing at the peak of the plague.

On April 21 (the fifteenth day of the third month of the lunar calendar), the peasant army arrived at Juyong Pass, and the Ming army surrendered without a fight.

On April 22 (March 17 of the lunar calendar), the peasant army entered Gaobeidian and Xizhimen and bombarded the city with artillery.

On April 24 (March 19 of the lunar calendar), in the early morning, Zhang Jinyan, the secretary of the military department, took the initiative to open the Zhengyang Gate to welcome Liu Zongmin's army; At noon, Li Zicheng entered from the Desheng Gate and entered the inner hall through the Chengtian Gate.

If we assume that the plague in Chongzhen's seventeenth year and SARS in 2003 follow the same weather and temperature curve, we can imagine the scene of the plague breaking out in Beijing in those days, so it is not difficult to understand why Zhu Youzhen decided to stick to Beijing in advance, and Li Zicheng would easily enter the city, and it can also be reasonably deduced that the peasant army was infected by the plague as soon as it entered the city, resulting in a significant drop in combat effectiveness.

In 2003, the number of people possibly infected by SARS plummeted after peaking, and the steepness of the decline coincided with the upward process.

On May 9, Beijing announced that the number of SARS cases in Beijing was on a significant downward trend. The average number of SARS infections among health care workers was 15.81 per day from April 21 to May 1, and 6.3 per day from May 2 to May 8.

On May 19, the number of new cases of SARS in Beijing dropped to single digits.

On June 10, Beijing maintained the "40" record of zero confirmed cases, suspected cases, previously suspected confirmed cases, and previously confirmed cases turned into suspected cases for three consecutive days.

On June 14, the World Health Organization lifted travel warnings for Hebei, Inner Mongolia, Shanxi, and Tianjin.

Of course, there are the fruits of the public efforts of the government and the people, but the proportion of human factors and weather factors is unknown.

In the seventeenth year of Chongzhen, Duoerhong entered Beijing on June 6. It can only be said that the Manchu Qing Dynasty had a really good life, just in time for the natural end of the plague.

After that, Duo Erhong ordered that all the inner cities of Beijing be emptied and changed to a "full city" where the Eight Banners were stationed, and the Han people were not allowed to enter. This move undoubtedly stopped the spread of the plague once and for all.

Even so, the Qing army did not dare to go deep into the epidemic area, or it was unable to go deep into the epidemic area. From May to October of the lunar calendar, the Qing army defied military common sense and did not take advantage of the situation to launch an attack on Nanjing, and the Southern Ming regime took the opportunity to establish.

Emperor Qianlong highlighted the Manchu Qing Dynasty's "righteousness of winning the country" and "rare and unparalleled". With a stroke of the pen, the head fell to the ground. The Beijing plague in the seventeenth year of Chongzhen disappeared in the history of the Qing Dynasty, and later generations can only get a glimpse of it in the wild history.

In English, history is called history, which means "his story". The so-called official history of the Qing Dynasty is just a "his story" told to you by Emperor Qianlong.
