It is said that it first began with the emperor's "tomb sacrifice" ceremony, which was passed down by the people and has been passed down to this day. The traditional Tomb-Sweeping Day in China began in the Zhou Dynasty and has a history of more than 2,500 years.

In ancient times, it was not as important as the Cold Food Festival the day before, because the dates of Tomb-Sweeping Day and the Cold Food Festival were close, and the people gradually merged their customs. In the Sui and Tang Dynasties, Tomb-Sweeping Day and Cold Food Festival gradually merged into the same festival, which became the day to visit graves and worship ancestors, that is, today's Tomb-Sweeping Day.
