What does the origin of Tomb-Sweeping Day mean in the allusions of Cold Food Festival?

Tomb-Sweeping Day is a traditional festival in China, and it is also the most important festival to worship ancestors and sweep graves. Grave-sweeping is commonly known as going to the grave and offering sacrifices to the dead. Most Han people and some ethnic minorities visit graves in Tomb-Sweeping Day. According to the old custom, when sweeping graves, people should bring food, wine, fruit, paper money and other items to the cemetery, offer food to the graves of their loved ones, then burn the paper money, cultivate new soil for the graves, break some green branches and insert them in front of the graves, then kowtow and worship, and finally go home after eating and drinking. The poem Qingming written by Du Mu, a poet in the Tang Dynasty, said: "There are many rains during the Qingming period, and pedestrians on the road want to break their souls. Ask local people where to buy wine? The shepherd boy pointed to Xinghua Village. " Write about the special atmosphere in Tomb-Sweeping Day. Tomb-Sweeping Day, also known as the outing festival, according to the solar calendar, between April 4th and 6th every year, it is the season of beautiful spring and lush vegetation, and it is also a good time for people to have a spring outing (called outing in ancient times), so the ancients had the custom of going for an outing in Qingming and carrying out a series of sports activities. There is also a saying in ancient times, that is, "March Festival". To this day, the custom of worshipping ancestors and mourning the dead relatives in Tomb-Sweeping Day is still very popular. Tomb-Sweeping Day is one of the traditional festivals of the Han nationality in China and one of the 24 solar terms in China, and the time is around April 5th in the solar calendar every year. In ancient times, it was said that the day before Tomb-Sweeping Day was the "Cold Food Festival". According to legend, it began in the Spring and Autumn Period when Jin Wengong mourned meson pushing "cutting stocks to satisfy hunger", and then gradually the Qingming cold food became one.

There is a legend: According to legend, during the Spring and Autumn Period and the Warring States Period, Shen Sheng was forced to commit suicide because her concubine set a poison plan for the prince in order to let her son inherit the throne. Shen Sheng's younger brother, Zhong Er, went into exile to escape the scourge. During his exile, Zhong Er suffered humiliation. Most of the courtiers who went out with him went out one after another. Only a few loyal people have been following him. One of them is called meson push. On one occasion, Zhong Er fainted from hunger. In order to save Zhong Er, Jiezitui cut a piece of meat from his leg, cooked it with fire and gave it to Zhong Er. Nineteen years later, Zhong Er returned to China and became the monarch, that is, Jin Wengong, one of the famous five tyrants in the Spring and Autumn Period. After Jin Wengong came to power, in addition to meson push, he offered many rewards to courtiers who shared his joys and sorrows. Someone defended meson in front of Jin Wengong. Jin Wengong suddenly remembered the past and felt guilty. He immediately sent someone to ask meson to take the imperial court to be rewarded as an official. However, after several trips, the meson could not be pushed. Jin Wengong had to please. However, when Jin Wengong came to the meson pusher's house, he saw that the door was closed. Jiezitui didn't want to see him, and had already been hiding in Mianshan (now southeast of Jiexiu County, Shanxi Province) behind his mother's back. Jin Wengong asked his body guard to search Mianshan, but he couldn't find it. So, someone had an idea, saying, it is better to let Yamakaji go, set fire on three sides, leave one side, burn it and the meson will come out. Jin Wengong ordered the promotion of Yamakaji. Unexpectedly, the fire burned for three days and nights. After the fire was put out, the meson was not pushed out after all. Looking up the mountain, the mother and son were holding a charred willow tree and were dead. Jin Wengong looked at meson push's body and cried for a while. Then I buried the body and found that the back of meson push was blocked by a willow hole, as if there was something. I took it out and saw that it was a skirt with a bloody poem written on it: May my Lord be in Tomb-Sweeping Day forever. It is better to be a ghost than to accompany you as an exhorter. If your master has me in his heart, remember that I often reflect. I have a clear conscience in Jiuquan, and Tomb-Sweeping Day Tomb-Sweeping Day is diligent. Jin Wengong hid the bloody book in his sleeve. Then meson tui and his mother were buried under the charred willow tree. To commemorate Jiexiu, Jin Wengong ordered Mianshan to be changed to Jiexiu Mountain, and an ancestral temple was built on the mountain, and the day when Yamakaji was released was designated as the Cold Food Festival, telling the whole country that it is forbidden to set off fireworks and firecrackers on this day every year and only eat cold food. When he left, he cut a charred willow and made a pair of clogs in the palace. He looked at it every day and sighed, "What a pity." The "first step" is the name of ancient people's subordinates respecting each other between superiors or peers, which is said to come from it. The following year, Jin Wengong led his ministers to go hiking in plain clothes to show their respect and condolences. Walking to the grave, I saw the dead old willow tree resurrected, with thousands of green branches dancing in the wind. Jin Wengong looked at the resurrected old willow tree and seemed to see the meson push. He walked up to him respectfully, lovingly squeezed a branch, braided it into a circle and put it on his head. After the sacrifice, Jin Wengong named the resurrected old willow "Tomb-Sweeping Day Willow" and named this day Tomb-Sweeping Day. Later, Jin Wengong often took a bloody book with him as a souvenir, urging himself to take power. He worked hard in Tomb-Sweeping Day and managed the country well. Since then, the people of Jin have been able to live and work in peace and contentment, and they are very nostalgic for Jietui, who has made outstanding contributions and is not looking for wealth. On the day of his death, it is forbidden to set off fireworks in memory of him. It is also made of flour and jujube paste into the shape of a swallow, strung with willows and inserted in the door to summon his soul. This thing is called "pushing swallows" (also called intermediary pushing). Since then, the Cold Food Festival and Tomb-Sweeping Day have become grand festivals for people all over the country. Whenever there is cold food, people don't make a fire to cook, but only eat cold food.
