Dujiangyan Qingming Water-Releasing Festival
The water-releasing festival is a ceremony dating back 1,000 years. It celebrates the completion of the Dujiangyan irrigation system and commemorates its designer Li Bing. The organizer usually hosts a series of tourism activities during the festival.
At the ceremony, actors imitated the ancient engineer Li Bing and his subordinates as they inspected the Dujiangyan irrigation system. Li Bing is the designer of the Dujiangyan irrigation system, and he served the state of Qin (221-206 BC) as an administrator. In May 2006, this folk custom was included in the first batch of national intangible cultural heritage list approved by the State Council.
According to historical record, the dam has stood for nearly 2,300 years, diverting water to irrigate nearly 70,000 hectares of farmland that produces almost one-third of the province's grain. It is considered to be the oldest functioning water-control project in the world.
Period: Qingming Festival, Tomb Sweeping Day, the fourth or fifth day of the fourth lunar month.
