There was a particularly hot year in China's history, and many people died. In which year and dynasty did it happen? What was the temperature then?

The hottest summer occurred in the eighth year of Qianlong (AD 1743).

It can be seen from the Meteorological Records of Qing Dynasty (I), the third volume of Meteorological Records of China for 3,000 years, that the high temperature in this year almost involved half of China, and the whole North China region such as Beijing, Tianjin, Hebei and Shanxi was extremely hot, which can be said to be super hot.

Beijing: "In June, Chen Bing (July 25th) was the capital of Shu Wei." ("Continued Donghua Record")

Tianjin: "May was bitter and hot, the earth and stone were brown, and gold flowed out from the masthead, and many people died of heat." (Tongzhi "Continued Tianjin County Records")

Gaoyi, Hebei Province: "From May 28th (July 19) to June 6th (July 26th), it was difficult to get hot, the wall was too cloudy, and it burned like fire. Lead and tin are sold out in Japan and China, and many people are dying of thirst. " (Gaoyi County Records of the Republic of China)

Fushan, Shanxi: "It is hot in May in summer, and many pedestrians on the road are killed by the heat, especially in Beijing, and some vendors floating in Beijing are also killed by the heat." (Qianlong's "Fushan County Records")

At that time, the whole North China region completely entered the "barbecue mode". "Continued Donghua Record" used "Shu Wei" to record the high temperature at that time. It's as hot as a tiger threatening to eat people, and it's fierce ~

According to the research conversion of Zhang Del, director of Paleoclimate Research Office of National Climate Center of China Meteorological Bureau and chief expert of climate change research, the temperature values of1July 20-25, 743 were all higher than 40℃. Among them, the temperature on July 25th was the highest, reaching an astonishing 44.4℃~
