Jie Zhitui was a virtuous minister of the State of Jin, who worked for Zhong Er (later Jin Wengong). There was civil strife in Jin, and his son Zhong Er was forced to flee abroad. Jie Zhitui went into exile with Zhong Er regardless of difficulties and hardships. Once I cut a leg to make soup and gave it to Zhong Er. After Zhong Er became a monarch, he remembered Jiezhitui at first, but after a long time, he was forgotten. Jie Zhitui felt very uncomfortable, so he returned to his hometown with his elderly mother and lived in seclusion in the mountains.
One day, Jin Wengong found that he was short of intermediaries, and he remembered that he had forgotten to reward the sage who "cut shares and serve the king". He felt very guilty and went to his secluded mountain to look for it himself. But I saw the overlapping mountains and trees, but I didn't see the shadow of the intermediary. Jie Zhitui is a dutiful son, he thought. If Yamakaji is released, he will definitely come out behind his mother's back. So, Yamakaji was ordered to release, and the fire spread for dozens of miles, and it didn't go out for three days, but it didn't come out. After the fire went out, everyone went into the mountain to see, only to find that Jie Zhitui and his old mother were burned to death in the mountain.
As soon as it came out, everyone respected and missed Jie tui. I will remember him on the day he was burned to death, that is, the day before Tomb-Sweeping Day in April every year. Because Jie Zhitui was killed by fire, everyone couldn't bear to light a fire on this day, preferring to eat cold food, so this day was called "Cold Food Festival".
