What festival is the Cold Food Festival related to?

During the Spring and Autumn Period, Zhong Er, the son of the Jin Dynasty, was exiled, hungry and dizzy on the way. I gave him the meat cut from his thigh. Zhong Er was very emotional, saying that he would be rewarded with meson push after he acceded to the throne in the future. Later, my son Zhong Er became Jin Wengong, and the loyal minister forgot to recommend him. When Zhong Er remembered this incident, Jiezitui refused to be an official again and lived in Mianshan behind his mother's back.

Zhong Er asked Yamakaji to force him out of the mountain, but the fire burned for three days and no one came out. He went up the mountain and found himself and his mother burned to death. On the charred willow tree, there is a big fairy who writes a bloody poem, "May the Lord be always clear when I cut meat and serve you." Therefore, Zhong Er designated the day when Yamakaji was released as Cold Food Festival.

The next day, Zhong Er climbed a mountain to pay homage, and found that the old willow was resurrected, so he named it "Qingming Willow" and named it Tomb-Sweeping Day. Throughout the country, it is forbidden to eat dry food and cold rice to commemorate Jiexiu, and encourage yourself to be diligent and clear to commemorate Jiexiu. This is the origin of the cold food festival, which is widely circulated among the people.

Extended data:

The dates of the Cold Food Festival have always been different. The Sui and Tang Dynasties were mostly two days before Tomb-Sweeping Day, and the Song Dynasty was three days before Qingming Festival. Generally speaking, the Cold Food Festival is celebrated from winter to the day after 105, so it is also called "Hundred Days Festival". Up to now, there are different opinions about whether Tomb-Sweeping Day celebrated the Cold Food Festival the day before, two days before or three days before.

Prohibition of fire is not a custom of cold food, and its origin can be traced back to the Zhou Dynasty. According to the literature records in the pre-Qin period, there was a strict system of banning fire at that time, and there was a custom that officials changed fire to serve the people. Zhou Li clearly recorded that there was a "torchbearer" at that time. Whenever the climate in mid-spring is dry, not only the kindling preserved by human beings is easy to cause fire, but also the occurrence of spring thunder is easy to cause mountain fires.

In this season, the ancients often held grand sacrificial activities to put out all the fires handed down from the previous year, that is, "no fire." Then rehearse it again and take out a new fire as the starting point of production and life in the new year. This is the so-called "changing fire". During the fire ban and changing fire, people must prepare enough cooked food and make a living by cold food.
