Cold food festival: after the summer solstice 105, one or two days before Tomb-Sweeping Day. When the first day of the day is a festival, smoking is forbidden and only cold food is eaten. In the development of later generations, customs such as sweeping, hiking, swinging, cuju, hooking and cockfighting were gradually added. The Cold Food Festival lasted for more than 2,000 years, and it was once called the largest folk festival in China. Cold Food Festival is the only traditional festival of Han nationality named after food customs.
The origin of the Cold Food Festival, according to historical records: During the Spring and Autumn Period, Zhong Er, the son of the State of Jin, fled into exile in other countries for 19 years, and the minister Jiezitui always followed around and never gave up; Even "cutting stocks." Zhong Er made great efforts to become a generation of famous monarch "Jin Wengong". However, Meson Tui did not want to get rich, so he retired to Mianshan with his mother. Jin Wengong ordered Yamakaji to be released in order to force him out of the mountain, but Meson Tui was determined not to go out of the mountain and eventually died of fire. Jin Wengong remembered his loyalty, buried him in Mianshan, built a shrine and built a temple, and ordered the ban on cold food on the day of Jietui's death, in order to express his grief. This is the origin of the "Cold Food Festival".
