1. During the Spring and Autumn Period, Zhong Er, the son of the Jin Dynasty, went into exile to escape persecution. In exile, in a deserted place, tired and hungry, I have no strength. The minister couldn't find anything to eat. When everyone was very anxious, a minister named Jiezitui went to a secluded place, cut meat from his thigh, cooked a bowl of broth and gave it to Zhong Er.

2. After drinking it, Zhong Er regained his spirits, only to find that the meat was cut off from meson's leg and shed tears.

3. Nineteen years later, Zhong Er became the monarch, that is, the historical Jin Wengong. After he acceded to the throne, in addition to meson push, he rewarded the princes who had wandered with him. Many people complained about meson push and advised him to ask for a reward. But mesons despise those who strive for merit and reward. He quietly went to Mianshan to live in seclusion.

4. After Jin Wengong knew it, he was ashamed and personally took someone to ask him to go down the mountain. But the meson pushed away and hid. Mianshan is densely forested, so it is difficult to find people. Some people put forward the plan of setting fire to push mesons from three sides, but Mianshan on the side of the big fire did not push mesons. After the fire went out, everyone found that Jiezitui had sat under an old willow tree and died.

5. Jin Wengong shouted. A bloody book was found in a tree hole, which read: "May my Lord be clear forever." To commemorate meson tui, Jin Wengong ordered that this day be designated as Cold Food Festival.

6. In the second year, Jin Wengong led the minister to climb the mountain to pay homage, and found that the old willow tree came back from the dead. He gave Laoliu the title of "Qingming Willow" and told the world that the day after the Cold Food Festival was designated as Tomb-Sweeping Day.
