Qingming Festival, also known as the Spring Festival, Xingqing Festival, March Festival, Ancestral Worship Festival, etc., is celebrated at the turn of mid spring and late spring. The Qingming Festival originated from the ancestral beliefs and spring festival customs of early humans, and is the most grand ancestor worship festival of the Chinese nation. The Qingming Festival combines both natural and cultural connotations, serving as both a natural solar term and a traditional festival. Tomb sweeping and ancestor worship, as well as outings, are the two major themes of the Qingming Festival. These two traditional themes of etiquette and customs have been passed down in China since ancient times and continue to this day.
