【Haichuan Teahouse】Do you know where the real four major hot spots are?

Thread Content

Chongqing, Changsha, and Wuhan have all fallen out of the list of the four hottest cities. The concept of these four hottest cities originated during the Republic of China era; they were the four cities located in the Yangtze River basin – Chongqing, Changsha, Wuhan, and Nanchang (the original four hottest cities) – and this classification was mainly due to the extreme heat in summer. At present, only Nanchang still holds the fourth position. Based on statistics over the 45-year period from 1973 to 2018, the top four cities were Haikou, Guangzhou, Nanning, and Nanchang. According to Figure 2, there are several combinations of the new four major hot cities, but regardless of the combination, Chongqing, Changsha, and Wuhan are not included. According to the statistics in Figure 1, Changsha ranks fifth and just falls out of the \"top four\", while Wuhan is in sixth place and Chongqing in ninth place. In fact, the top 20 cities are not very cool in the summer, but there’s no need to make a big deal out of it. Some people from the north say it’s cold in the south in winter because they have heating. In other words, it’s hot in the south during summer; luckily, air conditioning is available now.
