When is the Cold Food Festival? Is there customs?

Cold food festival is also called "smoke-free festival", "cold food festival" and "no fire festival". The Cold Food Festival is held from the winter solstice in the summer calendar 105, one or two days before Tomb-Sweeping Day. Before the calendar reform in Tang Ruowang in the early Qing Dynasty, Tomb-Sweeping Day was scheduled for two days after the Cold Food Festival. After the reform of the Tang family, the Cold Food Festival was held the day before Tomb-Sweeping Day. The definition of the modern twenty-four solar terms follows that of the Tang Dynasty, so the Cold Food Festival is the day before Tomb-Sweeping Day.

Cold Food Festival is an ancient festival in China with a history of more than 2,600 years. According to historical records, the origin of Cold Food Festival was decided by Jin Wengong in the Spring and Autumn Period to commemorate meson push. By the Tang Dynasty, it had become a national festival. On the day of the Cold Food Festival, smoking is forbidden and only cold food is eaten, hence the name. In the development of later generations, the customs of sweeping, climbing, swinging, cuju, crochet and cockfighting were gradually increased.

In history, the Cold Food Festival and the Qingming Festival are similar, and over time, they merged into one festival. According to the grand idea of China's traditional culture, "roughly in the Tang Dynasty, the Cold Food Festival and Tomb-Sweeping Day merged into one."
