What are the brief introductions of the legend of the origin of slight cold?

I grew up listening to fairy tales, and I often listen to some parents' stories, such as the story of Chinese New Year, the story of sister Chongyang and so on. It is rare to hear some legends about certain solar terms. When I grew up, I found that these stories actually existed on Baidu. So, what is the origin and legend of slight cold?

Introduction to Han Xiao

Slight cold, like severe cold, mild summer heat, severe summer heat and intense summer heat, are all solar terms indicating temperature changes. In the twenty-four solar terms, it is said that the cold at the beginning of the month is greater than that in the first half. In other words, in the Yellow River basin, the great cold was smaller and colder than then. And because the slight cold is still in the last few days of February 9, it will take several days to enter the period of March 9. The slight cold in winter just corresponds to the slight heat in summer, so it is called slight cold.

The solar term after the slight cold solar term is the great cold, and it is also very cold in April and September. At this time, Kuya sleeps like a camper, and the great cold in winter corresponds to the great heat in summer, so it is called the great cold.

The characteristic of slight cold is that the weather is getting cold gradually, but it is not cold yet. Midwinter March 9 is basically within this solar term, so there is a saying that slight cold is better than great cold. This is because on the solstice of last winter, the surface received the least sunlight and heat, but the heat in the deep soil supplemented this, so it was not the coldest time of the year. After the winter solstice, that is, around March 9, the heat in the deep soil was consumed. Although the sunshine and heat increased slightly, it was still beyond our capacity, so the lowest temperature in the whole year appeared.

The legend of Han Xiao

Legend 1:

Chang 'an in Tang Dynasty, the slight cold season is often not far from the twelfth lunar month. Because of the cold weather, it is popular in society to give gifts to each other. The emperor of the Tang Dynasty also had the traditional custom of giving oral fat and wax fat in barrels of ivory. In the twelfth lunar month of the third year of Jinglong in Tang Zhongzong, Zhongzong summoned his ministers in the imperial garden and gave him wax grease. At night, he entered the inner hall from the north gate and gave him food and oral grease.

Du Fu has a poem that says: oral fat powder medicine is accompanied by kindness, and the jade tube is in the clouds. Wang Jian's Gong Ci: When the waxwork is welcomed in the cold of the moon, the Jade Street is covered with snow. The name of the bathing hall (temple name) was copied outside, and the princess thanked her for being fat. Oral fat, namely lipstick. The flour medicine is to add anti-cracking medicine to wax grease. Therefore, apply oral fat and facial drugs to the face to prevent the lips from freezing and cracking in cold winter. Even now, these are still our necessities in winter.
