Qingming, the "Pure Brightness" or Tomb-Sweeping Festival, is a Chinese day for honouring the ancestors and the dead, kept in early April, about fifteen days after the spring equinox; unusually among Chinese festivals it is set by the solar terms of the traditional calendar rather than by the moon, falling on the day that opens the Qingming solar term, around 4-5 April. Its roots lie in ancient rites of ancestral reverence and in the older Cold Food Festival (Hanshi), with which it merged, and it gives expression to the deep Confucian value of filial piety (xiao) extended beyond death.
The festival's central act is the visit to the graves of the family's forebears: families travel, often long distances, to clean and tend the tombs, pulling weeds, repairing and sweeping the sites, and to make offerings of food, tea, wine and flowers, burning incense and, in a distinctive custom, paper money and paper models of goods for the use of the departed in the afterlife. The occasion also has a bright, outdoor side, coming as it does in spring: it is a traditional time for outings, walking in the new green, and flying kites, sometimes with lights attached for the night. Qingming thus binds the generations, cares for the dead, and welcomes the spring in a single observance, and it is a public holiday in China, Taiwan and among Chinese communities elsewhere.
