During the Spring and Autumn Period, the legend says that during the exile, Duke Chong Er of Jin went into exile to escape persecution. After searching for food for half a day, his attendants went to a secluded place and cut a piece of meat from his thigh and made a bowl of broth for him to drink. Nineteen years later, Chong Er became the ruler of the state, the historical Duke Wen of Jin. After his reign, the Duke of Jin rewarded all the officials who accompanied him into exile, but forgot about Jiezitui. Many people complained for Jiezitui and urged him to face the king to ask for rewards, but Jiezitui despised those who competed for rewards. He packed his clothes and quietly went to Mian Mountain to live in seclusion. When Duke Wen of Jin heard about it, he was ashamed and took his men to invite him personally, but he had already left home and gone to Mian Mountain. However, he had already left home and gone to Mian Mountain. The mountain was high and tree-lined, so it was not easy to find the two men. After the fire was extinguished, people found that Jie Zitui, who was carrying his mother on his back, was sitting under an old willow tree and died. When Duke Wen of Jin saw this, he wept. During the coffin, a bloody letter was found in a hole in the tree, which read, “I cut my flesh to serve you, but I wish my lord would always be clear.” To commemorate Jiezitui, Duke Wen of Jin ordered that this day be designated as the Cold Food Festival. The next year, the Duke of Jin led his ministers to climb the mountain to pay respects and found the old willow tree had come back from the dead. He gave the old willow tree the name of “Qingming Willow” and announced to the world that the day after the Cold Eclipse Festival would be designated as the Qingming Festival.
