The custom of tattooing the chin is one of the unique cultural features of the Mang ethnic group. Tattoos on each person's chin not only show the maturity of that person, but also show the spiritual concept of the Mang ethnic group.
Therefore, in the past
when Mang men and women reached the age of 12, they performed the chin tattoo ritual. The date chosen to hold the chin tattoo ceremony must be a beautiful day in the 10th lunar month every year.
Choosing a good day, the person with the chin tattoo and his family bring the offerings to the shaman's house for the ceremony, when everyone comes to the house, the shaman goes down to the top of the stairs to warmly welcome.
