The origin of cold solar terms

According to legend, the Cold Food Festival originated in the State of Jin in the Spring and Autumn Period to commemorate the courtiers of Duke Xiang of Jin. Zhong Er, the son of the State of Jin, went into exile 19 years. He was followed by guards and made great contributions. Zhong Er returned to the throne, that is, Jin Wengong. Jiezitui carried his mother and hid in Mianshan. Jin Wengong went to look for it, but he couldn't find it. So he released Yamakaji and tried to push the meson out. I didn't expect meson tui and his mother to hold a big tree, preferring to burn to death rather than go out of the mountain. Sadly, Jin Wengong ordered that Mianshan be renamed Jieshan (namely Jieshan in Jiexiu County, Shanxi Province) and that the day when mesons were burned to death be designated as Cold Food Festival. It is forbidden to make a fire and eat cold rice every year at the Cold Food Festival to show the meaning of remembering.

In fact, the real origin of the Cold Food Festival originated from the ancient system of drilling wood for new fire. Because of different seasons, the ancients used different trees to drill fires, which is the custom of making fires in different seasons. And every time you change the fire, you have to change it with a new one. People are forbidden to make a fire until a new one comes. This was a great event at that time. "Zhou Li Autumn Lawsuit Xuanjiashi": "In the middle of spring, it is forbidden to repair the fire with Muduo." It can be seen that he was walking in the street shaking the wooden head and ordered the fire to be banned. This is the company's propagandist, that is, a small official who specializes in making fires. When the fire is banned, people prepare some cold food to eat, which gradually becomes a fixed custom. Later, it was linked with the legend of meson push and became the Cold Food Festival, which lasted for one month. After all, it is unhealthy, so the date is shortened from seven days to three days and gradually changed to one day. After the Tang Dynasty, it was integrated into Tomb-Sweeping Day.
