Tomb-Sweeping Festival dates back over 2,500 years. The legend is it that around 650 BC, a man called Jie Zitui saved the life of Chong’er, a prince from the Jin principality, who was on the brink of starvation. The prince promised to reward Jie in the future. Nineteen years later, Prince Chong’er became Duke Wen. He ordered a search for Jie who had gone into hiding in the remote mountains with his mother. The duke wanted Jie to serve as one of his ministers. 

Jie, who preferred to be a hermit in the Mianshan Mountain in today’s Jiexiu city of Shanxi, had no political ambitions and refused the duke’s invitation. Chong’er ordered the mountain to be burned down to force Jie out of hiding. Unfortunately, Jie did not give in and the fire ended up killing him and his mother. 

To commemorate the man who saved his life whose life he had just ended, Duke Wen held a memorial underneath a willow tree, which returned from its burnt state to produce lush leaves and branches, unlike poor Jie. The Duke declared that no one should eat hot food on the anniversary of the tragedy. The tradition of eating cold food on Tomb Sweeping Day continues to this day.
