On the theme of "Tomb-Sweeping Day" [Qingming origin] Tomb-Sweeping Day is also called Youth Day.

Tomb-Sweeping Day, also known as the Walking Festival, is at the turn of mid-spring and late spring, that is, the first 108 day from winter to the future. It is a traditional festival in China, and it is also one of the most important festivals to worship ancestors and sweep graves. The traditional Tomb-Sweeping Day of the Han nationality in China began in the Zhou Dynasty and has a history of more than 2,500 years. Influenced by the Han culture, 24 ethnic minorities in China, such as Manchu, Hezhe, Zhuang, Oroqen, Dong, Tujia, Miao, Yao, Li, Shui, Jing and Qiang, also have the customs of Tomb-Sweeping Day. Although customs vary from place to place, grave-sweeping and outing are the basic themes.

Qingming was just the name of a solar term at first, and later became a festival to commemorate ancestors, which was related to the Cold Food Festival. Jin Wengong designated the second day of the Cold Food Festival as Tomb-Sweeping Day. In most parts of Shanxi, the day before Tomb-Sweeping Day was the Cold Food Festival. Some places, such as Yushe County, celebrated the Cold Food Festival two days before Tomb-Sweeping Day. Yuanqu County also pays attention to Tomb-Sweeping Day's Cold Food Festival the day before, and the light cold food the day before.

Tomb-Sweeping Day is one of the important "eight festivals a year" in China. Generally, it is around April 5 of the Gregorian calendar, and the festival is very long. There are two sayings: 8 days before 10 and 10 days before 10, and these 20 days belong to Tomb-Sweeping Day. Tomb-Sweeping Day originally meant grave-sweeping day, and the government of the Republic of China designated 15 days after the vernal equinox in 935 as a national holiday, also known as the national grave-sweeping day.

"Almanac": "On the fifteenth day after the vernal equinox, the bucket refers to Ding, which is used for Qingming, when everything is clean and bright, and when it is covered, everything is clean and bright, hence the name." As soon as Qingming comes, the temperature rises, which is a good time for spring ploughing and sowing, so there is a saying that "before and after Qingming, we plant melons and beans". [ 1]

It is said that the origin of Tomb-Sweeping Day began with the "grave-sweeping" ceremony of ancient emperors and generals. Later, people followed suit, and it became a fixed custom of the Chinese nation to worship ancestors and sweep graves on this day. On May 20th, 2006, it was approved by the State Council to be included in the first batch of national intangible cultural heritage list.
