The Qingming Festival, also known as the Treading Green Festival, is celebrated at the intersection of mid-spring and late spring, on the 108th day after the winter solstice. It is a traditional Chinese festival and one of the most important festivals for ancestor worship and grave sweeping . The traditional Qingming Festival of the Chinese people began around the Zhou Dynasty, more than 2,500 years ago.

Ching Ming was first known as a festival, and its transformation into a festival honoring ancestors is related to the Cold Food Festival. The day after the Cold Food Festival was designated as the Qingming Festival by the Duke of Jin. In most parts of Shanxi, the Cold Food Festival is celebrated one day before the Qingming Festival; in Yushe County and other places, the Cold Food Festival is celebrated two days before the Qingming Festival; and in Qiaqu County, the day before the Qingming Festival is the Cold Food Festival, and the two days before that are the Little Cold Food.

The Mid-Autumn Festival, also known as the Moon Festival, the Autumn Festival, the Mid-Autumn Festival, the August Festival, the August Festival, the August Meeting, the Moon Chasing Festival, the Moon Festival, the Moon Festival, the Moon Festival, the Daughter Festival, or the Festival of Reunion, is a traditional cultural festival that is popular among many ethnic groups in China and the countries of the Chinese Character and Culture Circle, on the fifteenth day of the eighth month of the Chinese lunar calendar; the name is given to it because it falls on the halfway point of the three autumns and there are also some places where it is set on the sixteenth day of the eighth month.

The Mid-Autumn Festival began in the early years of the Tang Dynasty, flourished in the Song Dynasty, and by the time of the Ming and Qing Dynasties, it had become one of the major Chinese festivals on a par with the Spring Festival. Influenced by Chinese culture, the Mid-Autumn Festival is also a traditional festival in some East and Southeast Asian countries, especially for the local Chinese diaspora. Since 2008, the Mid-Autumn Festival has been listed as a national holiday, and on May 20, 2006, the State Council included it in the list of the first national intangible cultural heritage.
