The origin of Tomb-Sweeping Day, why eat cold food?
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.
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. Since then, cold food and Qingming have become grand festivals for the people of the whole country. Whenever there is cold food, people don't make a fire to cook, but only eat cold food. Every time I go to Tomb-Sweeping Day, people put wicker in a circle and put wicker branches in front of the house to show their memory.
The traditional Tomb-Sweeping Day in China began in the Zhou Dynasty and has a history of more than 2,500 years. Qingming is a very important solar term at first, so there is an agricultural proverb that "planting trees is not as good as Qingming". Later, as the days of Qingming and cold food approached, cold food was the day when people banned fire from sweeping graves. Gradually, cold food and Qingming became one, and cold food became another name and custom of Qingming. On Qingming Day, there are no fireworks, only cold food.
