Qingming Festival, also known as Qingming Festival, Xingqing Festival, March Festival, Ancestral Worship Festival, etc., is a festival for worshipping, ancestor worship, and tomb sweeping between April 4th and 6th every year. The Qingming Festival originates from the ancestral beliefs and spring festival customs of ancient times, and combines both natural and cultural connotations. It is not only a natural solar term, but also a traditional festival. Qingming Festival, together with the Spring Festival, Loong Boat Festival and Mid-Autumn Festival, is known as the four traditional festivals in China.

The Qingming Festival is said to have originated from the "tomb sacrifice" ceremony of ancient emperors, kings, generals, and ministers. It dates back to the Zhou Dynasty and has a history of more than 2500 years. The Qingming Festival was originally just a name for a solar term, and it became a festival to commemorate ancestors and is related to the Cold Food Festival. Cold Food Festival and Qingming Festival are two different festivals. In the Tang Dynasty, the day of worshipping and sweeping tombs was designated as Cold Food Festival. During the Song and Yuan dynasties, the Qingming Festival gradually rose from being subordinate to the Cold Food Festival to replacing it. During the Ming and Qing dynasties, the tradition of worshipping ancestors and mourning deceased loved ones during the Qingming Festival was still prevalent, largely following the old system of the previous generation. During the Republic of China period, Qingming Festival was designated as Arbor Day in 1915, and the history of Qingming Festival as Arbor Day came to an end in 1928. Influenced by Han culture, ethnic minorities in China also have customs for the Qingming Festival. Although customs vary from place to place, tomb sweeping, ancestor worship, and outings are the basic themes of the Qingming Festival. In addition, there are many outdoor recreational activities such as swinging, cuju, kite flying, tree planting, tug of war, as well as food customs such as eating Zi Tuyan, Li Cheese, and Qingtuan. In addition to China, there are also some countries and regions in the world that celebrate Qingming Festival, such as Vietnam, South Korea, Malaysia, Singapore, etc.

On May 20, 2006, the Qingming Festival declared by the Ministry of Culture of the People's Republic of China was approved by the State Council and included in the first batch of national intangible cultural heritage list. In order to promote and inherit traditional ethnic culture, in 2008, Qingming Festival was designated as a national statutory holiday with one day off, and with weekends off, three days off were granted.
