To commemorate the meson push of Jin in the Spring and Autumn Period.

In the Spring and Autumn Period, Zhong Er, the son of the State of Jin, fled and had a hard life. The meson Tui who followed him cut a piece of meat from his leg to satisfy his hunger. Later, Zhong Er returned to the State of Jin, became a monarch (namely Jin Wengong), and raised a meritorious minister. Only meson tui refused to accept the reward.

He took his mother to live in seclusion in Mianshan and refused to come out. Jin Wengong was at his wit's end, so he had to release Yamakaji and force him to go down the mountain. Who knows that the mother and son would rather be burned to death than come out. To commemorate Jiezitui, Jin Wengong ordered Mianshan to be renamed Jieshan, and a temple was built to erect a monument. At the same time, it also ordered that on the day of the death of meson tui, "cold food is forbidden to fire", and the whole country is not allowed to cook food by fire, so it can only eat dry food and cold food.

Customs of Cold Food Festival:

1. Cold Food Diet: On the day of Cold Food Festival, people will prepare cold noodles and cold food in advance. On this day, they will eat a kind of porridge called cold food porridge. It's porridge made of wheat and rice, and green rice, which is a kind of black glutinous rice. Both of them will be eaten on this day.

2, cold food willow: On this day, people will put wicker in front of the door, which means it is used to ward off evil spirits and disasters, which can protect the safety of their families. Moreover, the inserted wicker is also exquisite, and it must be the kind of wicker that stands upright to the sky to be useful.

3. Flying kites in cold food: Kites have a history of more than 2, years. It is said that kites were used to deliver letters and information in wars at that time, but now they have gradually become a tool for people to play. Writing down their troubles on kites and letting them fly away is equivalent to letting them take away their troubles and taking away disasters and bad luck by kites, so people will not pick up kites, thinking that they are on kites.
