The Festival, which dates back to the 11th century as a religious activity for pilgrims to serve yogurt to monks and nuns who finished their summer retreat, had gradually become a theatrical event by mid-17th century. The Shoton Festival was inscribed on the list of China Intangible Cultural Heritage in May last year. [Xinhua]
