The Qingming Festival or Ching Ming Festival, also known as Tomb-Sweeping Day in English (sometimes also called Chinese Memorial Day, Ancestors' Day, the Clear Brightness Festival, or the Pure Brightness Festival), is a traditional Chinese festival observed by ethnic Chinese in mainland China, Hong Kong, Macau, Taiwan, Malaysia, Singapore, Cambodia, Indonesia, Philippines, Thailand, and Vietnam. A celebration of spring, it falls on the first day of the fifth solar term (also called Qingming) of the traditional Chinese lunisolar calendar. This makes it the 15th day after the Spring Equinox, either 4, 5 or 6 April in a given year. During Qingming, Chinese families visit the tombs of their ancestors to clean the gravesites and make ritual offerings to their ancestors. Offerings would typically include traditional food dishes and the burning of joss sticks and joss paper. The holiday recognizes the traditional reverence of one's ancestors in Chinese culture.
The origins of the Qingming Festival go back more than 2500 years, although the observance has changed significantly. It became a public holiday in mainland China in 2008, where it is associated with the consumption of qingtuan, green dumplings made of glutinous rice and Chinese mugwort or barley grass.
In Taiwan, the public holiday was in the past observed on 5 April to honor the death of Chiang Kai-shek on that day in 1975, but with Chiang's popularity waning, this convention is not being observed. A confection called caozaiguo or shuchuguo, made with Jersey cudweed, is consumed there.
A similar holiday is observed in the Ryukyu Islands, called Shīmī in the local language.
There will be a 3days holidy in China, Tomb-Sweeping Day, from April 4th to April 7th.
