Qingming Festival is when Chinese people traditionally visit ancestral tombs to sweep them. This tradition has been legislated by the Emperors who built majestic imperial tombstones for every dynasty. For thousands of years, the Chinese imperials, nobility, merchants, and peasantry alike have gathered together to remember the lives of the departed, to visit their tombstones to perform Confucian filial piety by tombsweeping, to visit burial grounds, graveyards or in modern urban cities, the city columbaria, to perform groundskeeping and maintenance and to commit to pray for their ancestors in the uniquely Chinese concept of the afterlife and to offer remembrances of their ancestors to living blood relatives, their kith and kin. In some places, people believe that sweeping tomb is only allowed during this festival, they believe dead will get disturbed if sweeping on other days.
