Yudu was a historical Korean summer festival centered on the practice of washing one's hair to remove misfortune [1].

The tradition represents an intersection of hygiene and spirituality, reflecting how ancient societies used seasonal rituals to seek mental and physical renewal. As modern lifestyles replace traditional customs, the decline of Yudu highlights the erosion of ancestral cultural practices in the region.

Participants in the festival believed that the act of washing their hair on this specific day would rid them of bad luck [1]. This ritual served as a symbolic cleansing process, intended to prepare individuals for the challenges of the coming months. The festival took place during the summer, though the specific calendar date varied by historical observation [1].

While the festival was once widely celebrated across Korea, it has since transitioned from a common public event to a forgotten custom [1]. The practice of washing away misfortune through water-based rituals was a central pillar of the Yudu experience.

Few contemporary records or active celebrations remain to sustain the tradition in the modern era. The shift away from these rituals suggests a broader trend of urbanization, and the loss of agrarian-based seasonal celebrations in Korean society [1].

The disappearance of Yudu illustrates the tension between rapid modernization and the preservation of intangible cultural heritage. When ritualistic practices tied to seasonal cycles vanish, communities lose specific historical frameworks for addressing misfortune and psychological stress.
