China Weather TV released its 'stove ranking' - the new list of hottest cities on mainland China - on Sina Weibo, a micro-blog service provider in China.

Fuzhou of Fujian province tops the list, followed by Chongqing, Hangzhou of Zhejiang province and Haikou of Hainan province.

According to the micro-blog, there were more days with temperatures above 35 C in the past 30 years, from 1981 to 2010. The number of days increased most sharply in South China, including Guangzhou (7.7 days), Fuzhou (5 days) and Haikou (5 days). Fuzhou has overtaken Chongqing to become Chinese mainland's "hottest stove" in provincial capital-level cities.

"Stove ranking" is not something new in China. Nanchang of Jiangxi province, Chongqing, Wuhan of Hubei province and Nanjing of Jiangsu province make the top four of the most traditional list. In 2010, Chongqing, Fuzhou, Hangzhou and Nanchang were named the new four "hottest stoves" on the mainland.

However, these two versions have no scientific basis. Instead, they just reflect people's opinions. Meteorologists then set up a heat index, which reflects the influence on bodily comfort by temperature and humidity, and gives the calculation formula. The higher the index, the less comfortable people will feel. Meteorologists suggest days with an index above 85 be called "hot days".

Here is the full list:

1 Fuzhou, Fujian province

2 Chongqing

3 Hangzhou, Zhejiang province

4 Haikou, Hainan province

5 Changsha, Hunan province

6 Nanchang, Jiangxi province

7 Wuhan, Hubei province

8 Nanning, Guangxi Zhuang autonomous region

9 Xi'an, Shaanxi province

10 Guangzhou, Guangdong province

11 Shijiazhuang, Hebei province

12 Zhengzhou, Henan province

13 Hefei, Anhui province

14 Nanjing, Jiangsu province

15 Jinan, Shandong province

16 Shanghai
