Traditionally the family tomb is cleaned and swept on Qing Ming day with fresh offerings laid out for the ancestors. This festival is anchored to the solar year rather than lunar year and so always falls between April 4th to 6th. It marks the start of Spring and is associated with kite flying. It has similarities to the Christian Easter Spring festival in that eggs are prepared and eaten. In some areas boys used to wear willow wreathes on their heads to summon rain for the growing season.
