Following the incense offering and rituals to invite Miss Han to join the festival, selected women are divided into two groups to go down to the river to wash their hair. This act symbolises cleansing away all misfortunes of the past year and welcoming the new year with good luck, peace, and abundant harvests. 

Recognising its cultural and traditional significance, in 2020, the Ministry of Culture, Sports and Tourism officially inscribed the festival into the National List of Intangible Cultural Heritage.
