1. Qingming Festival, also known as the outing festival, according to the solar calendar, it is between April 4 and 6 every year. It is a beautiful time for grass and trees to turn green in spring, and it is also a good time for people to travel in spring (called outing in ancient times). Therefore, the ancients had the custom of Qingming outing and carried out a series of sports activities. In ancient times, there was another saying, "March Day".
2. Qingming Festival is an important traditional folk festival in China. It is one of eight important festivals: Shangyuan Festival, Qingming Festival, Beginning of Summer Festival, Dragon Boat Festival, Zhongyuan Festival, Mid Autumn Festival, Winter Solstice and New Year's Eve. Generally, it is on April 5 of the Gregorian calendar, but the festival lasts for a long time. There are two versions: eight days before the tenth day and ten days before the tenth day. These two versions belong to Tomb Sweeping Day in the past twenty days.
3. The origin of the Tomb Sweeping Day is said to have begun with the ritual of "offering sacrifices to the tombs" of ancient emperors and generals. Later, people followed suit, offering sacrifices to ancestors and sweeping tombs on this day. It has been a fixed custom of the Chinese nation for generations. Originally, Cold Food Festival and Tomb Sweeping Day were two different festivals. In the Tang Dynasty, the day of worship and tomb sweeping was designated as Cold Food Festival.
