Don't be foolishly self-righteous. Not the vast majority of things in this world are what you think they are, they can be outside your cognition.

Question 1: What are long johns?

Long johns are indeed autumn johns, but they are not necessarily worn in autumn. In fact, it refers to trousers worn under wool pants, cotton pants or other outer pants to keep warm when the temperature is relatively cold. Why add "autumn" here, this unique seasonal vocabulary? This is a pair of trousers in season. Autumn happens to be the season when the temperature starts to get cold. In early autumn, the body feels comfortable and cool, and gradually it will become cold. When the temperature reaches about 10℃, you can wear beautiful long johns.

Therefore, long johns are thermal underwear, and when the temperature is lower than 10 °C, wear pants that keep warm inside the outer pants.

Question 2: What season do you wear the long johns?

Generally speaking, the autumn in southern China is coming to an end, and the winter comes, the temperature will be around 10℃; the autumn in northern China will start with a temperature of around 10℃.

Therefore, long johns are thermal underwear worn in autumn.

Question 3: Who invented the long johns?

This is a warm thing! So, back to its roots: Who invented the long johns?

According to online news, johns originated in the North American continent and was designed by a Canadian Frank Stanfield. On December 7, 1915, it officially applied for and obtained the patent for long johns. He and his brother started out with cotton underwear known as "non-shrinking" and became the father of modern commercial long johns.

In 1915, long johns were not yet popular, and the "rompers" were mainly popular, that is, the combination of long underwear. Until 1918, various countries started daily production. Due to different labor methods, manual laborers who originally moved their whole bodies were divided into laborers with more upper body activities and laborers with more lower body activities. Therefore, the disadvantage of jumpsuits compared with long underwear is gradually obvious. Since then, long johns are more popular than jumpsuits, ushering in the spring of long johns.

After 1959, with the development of science and technology and the improvement of people's aesthetics, the European and American people noticed that the long johns were not very beautiful and fashionable. With the improvement of heating and living conditions, fewer and fewer people would wear long johns when it was cold.
