Is there a particularly hot year in history?

In the summer of the eighth year of Qianlong (AD 1743), the history books recorded it as "the hottest summer in history". It is said that a foreigner happened to be traveling in China at that time. He said in the record that he had never seen such high temperature as 1743, which killed many poor and fat people and caused widespread panic. In many official records, there have been records about this extreme weather. The average temperature in dog days reached 40 degrees Celsius, and the highest temperature reached 434 degrees Celsius.

"Tianjin County Records" records: May was bitter and hot, earth and stone were browned, gold flowed out from the masthead, and many people died of heat;

"Continued Donghua Record" records: Chen Bing in June, Shu Wei, Shi Jing.

"Qingcheng County Records" records: the drought is thousands of miles away, indoor appliances are hot, and wind-baked trees are dry in the southwest.

From some records, we should be able to see that the degree of heat at that time was beyond people's imagination, and there were deaths caused by large areas of high temperature in many places, but even if people prayed for blessing, it had no effect. According to statistics, the death toll near the capital at that time exceeded 10000.
