In the south of Huaihe River, it is called cotton trousers, and in some places it is also called underpants and thread trousers. Autumn trousers belong to underwear and can't be worn outside. Moreover, the degree of warmth is second only to that of warm pants, which can effectively prevent cold.

After World War I, countries returned to daily production, and European and American countries deepened the industrial revolution according to the idea of assembly line and division of labor. In the past, manual workers with full-body activities were divided into workers with more upper body activities and workers with more lower body activities. Even places where shirts and trousers were not as good as autumn clothes for autumn trousers appeared, and autumn trousers ushered in their own spring.
There was no such perfect indoor heating condition in America in the 1940s and 1950s. In winter, many people keep warm in the stove. At that time, I not only wore long-sleeved clothes or jumpsuits indoors, but also wore nightcaps when I slept. The frequency of taking a bath is far from the current level of taking a bath every day-the reason is simple, not to mention how to prepare hot water. Freezing your hair after washing it is a big problem.
The same was true in China 30 years ago. Every household relied on coal stoves to keep warm and collective bathhouses to take a bath. There were also folk customs such as "No shaving before February 2nd" and "No bathing in the first month".
A saying on the Internet: Before 1960, American farmers could spend the whole winter in jumpsuits without changing clothes. At first, Hu felt incredible, so he simply asked several generations of residents living in the United States.
One of them is outspoken about this history, saying that it is obviously an extreme situation not to change "long underwear" all winter, but it is a fact that underwear is not changed often-his grandfather's long pants often give off an unforgettable strong smell. As for southerners, they seldom wear long trousers, but they have all heard of them, which shows that long trousers are famous in the United States.
The United States was still like this in the 1950s, and other countries can imagine it. No wonder Khrushchev questioned the technological level of Nixon's "typical American residence" during the 1959 "Kitchen Debate" between the United States and the Soviet Union. Judging from the historical reference of autumn trousers, the electrical appliances displayed in the United States in that year may indeed be a little ahead of the times.
As time goes by, Europeans and Americans pay more and more attention to the fact that autumn trousers are not so beautiful and fashionable, and with the improvement of heating and living conditions, fewer and fewer people will wear them. Up to now, it has become synonymous with soil, which shows that the concept of autumn trousers has changed a lot.
