report their names for awards". Jie, however, was overlooked and felt so sad that he retired to the countryside, carrying his mother on his back. Recalling his loyal follower months or years later, Chong'er personally wandered the forests and ridges looking for them. His new advisors suggested using a forest fire to drive Jie out, since his duty to his mother would overwhelm any other concerns. The fire was started on one or three sides, and men waited on the open end to welcome the official back into public service. Instead, the fire raged for three days and nights and the mother and son were found burnt to death beneath a willow. In his sorrow and guilt, Chong'er renamed the mountain after Jie. (The surrounding territory would also later take the name "Jiexiu" or "[Place of] Jie's [Final] Rest".) He also ordered a period of prohibition against fire in Jie's honor, forcing the people to eat cold food during three days around the Qingming solar term. In fact, the Cold Food Festival is not attested before the Han and began as a month-long popular observance to placate Jie's spirit in the depths of winter. The hardship this caused—including death among infants and the elderly—caused it to be repeatedly banned over a period of centuries. The regulations succeeded in moving the festival to the end of spring (by Chinese reckoning), but it never died out in Shanxi and spread through the rest of China under the Sui and Tang. Aspects of ancestral veneration added to it from the old Double Third Festival eventually overshadowed the stories of Chong'er and Jie Zhitui, however, causing it to develop into the modern Tomb-Sweeping Festival instead.
