The origin and custom of intense heat
On July 7th or 8th every year, when the sun reaches longitude 105, it is considered as a slight summer heat. "Twenty-four solar terms": "June solar terms, summer heat, summer heat is also divided into sizes, small at the beginning of the month, large in the month, and still small today." Summer is hot. The ancients thought that the summer heat period was not the hottest time of the year, so it was called summer heat.
2. Customs
People have the custom of eating three treasures in summer, that is, eel, honey lotus root and mung bean sprouts. In the past, Xiaoshu had the custom of "eating fresh food". People grind newly beaten rice and wheat into flour, make all kinds of cakes and noodles, and share them with their neighbors to express their wishes for a bumper harvest. At the same time, these foods should also be prepared as sacrifices for ancestors, and please bless the good weather. In summer, people will also choose to "bask in the sun" and hang their clothes in the cupboard outside to receive the sunshine.
Climatic characteristics of light summer heat
The average summer temperature in southern China is generally around 33℃. In the low-altitude valley area of southeastern South China, the average daily temperature in mid-July is higher than 30℃, and the maximum daily temperature is higher than 35℃. In the northern part of the northwest plateau, frost and snow can still be seen at this time, which is equivalent to the scene of early spring in South China.
After the slight summer heat, the eastern part of South China began to enter the summer drought period due to the frequent control of subtropical high and frequent sunny and hot weather, and the southern part should pay attention to drought resistance after the slight summer heat. This year's dive time is July 17, which is the first 10 day after the arrival of the summer heat.
