It involves a ritual performance where mediums, often women, enter a trance to communicate with deities and spirits. The practice is characterized by vibrant costumes, music, and dance, creating a lively atmosphere that attracts participants and spectators alike. During the ceremony, the medium embodies various deities, offering blessings and guidance to attendees. Hầu Đồng serves as a way for people to seek spiritual support, celebrate cultural heritage, and connect with their ancestors, making it an important aspect of Vietnamese spirituality.
