What is the traditional story of winter solstice and the legend of winter solstice solar terms?

Winter Solstice Legend: From the ancient emperors-Huangdi and Yao Di.

There are two theories that the Winter Solstice Festival originated from the Yellow Emperor and Yao Di. According to the Historical Records of Xiaowu, a minister said to Emperor Wu of the Han Dynasty, "Did the Yellow Emperor win the Baoding God? (or Jia), it was the winter when I was sixty, and it was also the beginning of a day. So the Yellow Emperor welcomed his grandson? After I was 20 years old, I won the winter solstice. "

This record shows that the Yellow Emperor took the winter solstice as the beginning of the year and took "Shuodan", but there is no such record in the Historical Records of the Yellow Emperor Stupid Chicken, so it is difficult to test the isolated evidence. Another way of saying it is that Emperor Yao ordered his uncle He to live in the north, observe the movement of the sun, and then determine the time of winter. "Shangshu Yu Shu Yaodi" once said: "(Yaodi) declared that he and his uncle would live in the north and called him a secluded capital. Ping is in Yi Shuo. The day is short and the star is long. It is already mid-winter. " (press: new moon, north also. )

Shangshu's completion time is closer to Yao Di's era, and its documents are more reliable, and the historical materials contained in it may be closer to historical facts. It can be seen that the winter solstice, as a festival, has been paid attention to in ancient China.
