Why is it so hot in early autumn?

Beginning of autumn doesn't mean that the hot weather is over. The so-called "heat is in the dog days" and "it drops after autumn" means that there is at least a "drop" of heat after beginning of autumn.

According to the traditional dog days calculation method, its date is determined by the date of the solar term and the date of the dry branch. According to the folklorist Xiao Fang, beginning of autumn determined the start date of autumn based on the astronomical observation of the earth's orbit around the sun.

Therefore, beginning of autumn marks the beginning of seasonal changes, but it doesn't mean that the temperature will drop immediately. After the solar term in beginning of autumn, it is often the last day, and it is inevitable that you will sometimes feel the afterglow of the "autumn tiger".

From this point of view, a day in beginning of autumn is not a watershed in the heat. People really feel the coolness of autumn, usually after the Millennium solar terms.

The ritual sense of beginning of autumn solar terms cannot be less

Among many customs in beginning of autumn, "gnawing at autumn" is a ritual custom. Autumn is the harvest season, and people have the custom of offering sacrifices to the land gods and celebrating the harvest. The south will be "beginning of autumn gnawing at autumn melons".

In some places, "biting autumn" is called "biting autumn", which means that the heat is unbearable. Speaking of beginning of autumn, we should take a bite. In early autumn, Jiangsu and other places eat watermelon to "bite the autumn". It is said that prickly heat in autumn can be avoided.

A bumper harvest of fruits and vegetables always brings joy to people. Sunbathing in autumn at this time is a typical agricultural custom phenomenon. People living in Hunan, Jiangxi, Anhui and other places will use the front and back of the house and their own windowsills and roofs to dry crops, which is quite poetic.

At the beginning of autumn, people weigh themselves with hanging scales and compare their weights in the long summer. In fact, it's too hot in summer, and people can easily lose weight because of "bitter summer", so when they are in beginning of autumn, they have to cook all kinds of delicious food, such as braised pork, which is called "sticky autumn fat".
