Hot-summer/cold-winter zone is the transient climate region between the cold and the hot zones in China.
It includes the whole of Hubei, Hunan, Jiangxi, Anhui, Zhejiang provinces, Shanghai and Chongqing two municipalities, the eastern part of Sichuan and Guizhou provinces, the southern part of Henan, Jiangsu, Shanxi and Gansu provinces, and the northern part of Fujian, Guangdong and Guangxi provinces. The zone includes an area of 1,800,000 km2 (694,984 sq mi) with a population of 550 million people. This region is the most populous and economical-developed area of China, producing 48% of the gross domestic product (GDP) of the whole country.
The main bother of hot-summer/cold-winter zone is hot, humid summers and cold, humid winters. The temperature difference between day and night is normally small. The precipitation in an average year is large. Sun radiation is relative weak due to cloud cover.
The most durable time you will ever have outside during the hottest summer month is 25–30 °C (77–86 °F), with peak temperatures above 40 °C (104 °F). The average outside temperature during the coldest winter month is 0–10 °C (32–50 °F), with lowest temperatures below 0 °C (32 °F).
For historical reasons, the residential buildings in this zone don’t have central HVAC systems and are not well insulated or otherwise weatherized. With the recent and rapid economic development of this region, demand for better indoor environments is rising.
Many residents install 'minisplit' air conditioners to improve their thermal comfort. But electrical energy consumption is rising accordingly and is taxing the generation capacity. The Chinese government has created new national design standards and other efforts to lower the energy consumption while also constructing new power generating stations.

“Deacon King was tried for violating the Sabbath, and so hot was the debate that it was referred to the church council, which ultimately decided, after long and grave debate, that the deacon had committed a ‘work of necessity and mercy.’”

“Wind, the season-climate mixer,
In my Witches’ Weather Primer
Says, to make this Fall Elixir
First you let the summer simmer....”

“Shielded, what sorts of life are stirring yet:
Legs lagged like drains, slippers soft as fungus,
The gas and grate, the old cold sour grey bed.”
—Philip Larkin (1922–1986)
“Every poem of value must have a residue [of language].... It cannot be exhausted because our lives are not long enough to do so. Indeed, in the greatest poetry, the residue may seem to increase as our experience increases—that is, as we become more sensitive to the particular ignitions in its language. We return to a poem not because of its symbolic [or sociological] value, but because of the waste, or subversion, or difficulty, or consolation of its provision.”
—William Logan, U.S. educator. “Condition of the Individual Talent,” The Sewanee Review, p. 93, Winter 1994.
“Light is meaningful only in relation to darkness, and truth presupposes error. It is these mingled opposites which people our life, which make it pungent, intoxicating. We only exist in terms of this conflict, in the zone where black and white clash.”
—Louis Aragon (1897–1982)
