According to historical records, on a certain day in the eighth year of Qianlong, 1 1400 people died of heatstroke. What's the temperature?

In the eight years of Qianlong in Qing Dynasty, a serious meteorological disaster occurred, when the weather was particularly hot, which was called the hottest summer in China's history. At that time, the conditions were not good, there was no air conditioner and no fan, and the medical conditions could not keep up. Even Emperor Qianlong, who could enjoy the best treatment, once wrote poems complaining about how hot the weather was. Emperor Qianlong wrote about the situation at that time: ice trays and snow rafts turned cold. Tossing and turning, my heart is in Guizhou and my body is in Lebanon.

Emperor Qianlong used ice cubes to cool down in the summer resort and fanned the wind with a fan. It felt so hot, not to mention ordinary people. According to historical records, in that summer, the number of deaths in Beijing and its suburbs in the Qing Dynasty was about 1 1400 in two days, instead of 1 1400 in one day. This is a terrible number, and only in Beijing and its suburbs.

According to the research of the laboratory of China Meteorological Bureau, the average summer temperature in Qianlong eight years in Qing Dynasty was around 40℃, and it reached 44.4℃ in the twelve days when people died of heat, and the surface temperature was close to 65℃. What is the concept of such a high temperature?

Usually when the temperature exceeds 25℃, we have to put on a mat to sleep. At 30℃, we need to shake the fan and blow the air conditioner. It's cooler at night in summer, but we still need to turn on the air conditioner and adjust it to about 26℃. Usually it's above 35℃ in summer, and everyone doesn't want to go out, so they all eat iced watermelons under air conditioning, so think about how horrible 44℃ is.

In the Qing dynasty, if people didn't have ice in their homes, they had to shake fans under trees, but many people still had to run for their lives. Farmers work in the fields, vendors sell goods in the streets, and guards guard the city. Without good cooling conditions and effective heatstroke prevention measures, many people will die naturally in such a hot temperature.
