Qingming Festival is one of the twenty-four solar terms of the lunar calendar. It occurs at the turn of mid-spring and late spring, which is 108 days after the winter solstice. The traditional Qingming Festival of the Chinese Han people began around the Zhou Dynasty and has a history of more than 2,500 years. "Almanac": "On the fifteenth day after the spring equinox, when the fighting fingers are ding, it is the Qingming Festival. At that time, everything is clean and clear. At this time, the air is clear and the scenery is bright, and everything is visible, hence the name." Once the Qingming Festival comes, the temperature rises, It is a good time for spring plowing and spring planting, so there is a saying that "before and after the Qingming Festival, plant melons and beans." Qingming Festival is a festival for worshiping ancestors, and the traditional activity is tomb sweeping. On May 20, 2006, it was approved by the State Council and included in the first batch of national intangible cultural heritage lists.

Tomb-sweeping Festival is a traditional Chinese folk festival. It is one of the important "eight festivals" (Shangyuan, Qingming, Beginning of Summer, Dragon Boat Festival, Zhongyuan, Mid-Autumn Festival, Winter Solstice, and New Year's Eve). It usually falls in April of the Gregorian calendar. Around the 5th, the festival is very long. There are two versions: 10 days before and 8 days after, and 10 days before and 10 days after. The past 20 days are all Qingming Festival. [1]

To talk about Qingming Festival, we need to start with a lost festival - Cold Food Festival [1].

The Cold Food Festival, also known as the Hot Food Festival, the No-Smoking Festival, and the Cold Festival, is 108 days away from the winter solstice, which is only one or two days away from the Qingming Festival. The main custom of this festival is the prohibition of smoking. Fire, no fire is allowed for cooking, only prepared hot food and cold food can be eaten, hence the name.

The origin of the Qingming Festival is said to have begun with the ceremony of "grave sacrifices" for emperors, generals and prime ministers in ancient times. Later, the people also followed suit, worshiping ancestors and sweeping their tombs on this day, which has been followed by generations and has become a fixed custom of the Chinese nation. .
