In the early days of the rule, China's economy, politics and culture reached their peak, and its prosperity greatly exceeded that of all previous dynasties, including Han and Tang Dynasties. The great development of agriculture in Qianlong period was due to social stability. The Qing court in the Central Plains attached importance to agricultural production, rewarded reclamation and reduced taxes. However, during the Qianlong period, China ushered in the hottest summer in history, which really made us imagine that when there was no air conditioning, people could not enjoy products comfortably in cold and hot as in modern times. At the temperature of 40 degrees, people have to live and work in hot weather. In June of the eighth year of Qianlong, because the weather was too hot, the water was evaporated and there was no water to drink. Everyone died of thirst. The furniture, utensils, pots and pans at home are extremely hot, and the heat can only be dissipated by drinking water. It's hard to sleep on a sultry night. Moreover, unlike modern times, there was sunscreen for air conditioning in ancient times. Coupled with the feudal heat at that time, it was necessary to wear long clothes to cover the whole body. It's hot to think about it. Therefore, I think it is not an exaggeration for tens of thousands of people to die of heat at that time, and some archaeologists have confirmed that it is true. I'm glad I was born in 2 1 century, and my living standard is not bad.
