Which three cities are Sanzao?

A stove refers to a hot city in summer. It first began in the Republic of China, when Chongqing, Wuhan, Nanjing and other places in the middle and lower reaches of the Yangtze River were hot in summer, so it was called "three stoves".

During the Republic of China, there was a high temperature area in the middle and lower reaches of the Yangtze River in China in summer, including Nanjing, Wuhan and Chongqing. The highest temperature in China and Japan exceeds 30℃ for more than 70 days in a year, and there have been high temperature weather above 40℃, so people also call these three cities "three stoves".

It doesn't mean the unusually high temperatures in these three cities, but as well-known cities, their enthusiasm is easier to be remembered and publicized by literati in past dynasties.

Form a background:

On July 24th, 2065438+May, the extreme maximum temperature of 50.3℃ in China was observed in Aiding Lake, Turpan Basin, China. However, it is small in size and population, and it is hot but not stuffy. Therefore, in the hottest summer of the year, it is not Turpan that has the greatest influence on people's life and work in China, but the Yangtze River basin with a vast area and a large population.

There are three most famous "big stoves": Nanjing, Wuhan and Chongqing. During the Republic of China, the three stoves in Nanjing, Wuhan and Chongqing were really hot. The average maximum temperature in the hottest month is about 32 ~ 34℃, and the extreme maximum temperature is 39.6 ~ 43.0℃. The high temperature lasts for a long time, and the average number of hot summer days above 30℃ is over 70 days every year, from morning till night.
