The Mother Goddess Lieu Hanh holds a paramount position in Vietnamese belief systems, particularly within the context of the Mother Goddess worship. She amalgamates elements from Confucianism, Buddhism, Taoism, and indigenous goddess veneration to promote virtuous behavior, punish wrongdoers, vanquish adversaries, and safeguard the nation and its people across the regions she traversed. Employing a combination of ethnographic fieldwork, in-depth interviews, and participant observation, this article explores the enduring influence of Mother Goddess Lieu Hanh in the locale of Phu Vang, situated in the Hoang Hoa district of Thanh Hoa province. Drawing upon empirical data collected in the region, this research unveils the historical roots of Phu Vang, a place of solemn worship for the Mother Goddess, with origins dating back to the 18th century. Additionally, the study spotlights the profound impact of the Mother Lieu Hanh Goddess on the local cultural heritage. According to legend, the Nguyen Dynasty's royal decree granted Dai Dien village the privilege of venerating the Mother Goddess. Simultaneously, the Phu Vang Festival, held on the anniversary of Mother Lieu's passing, vividly illustrates the role and influence of worshipping Mother Goddess on the spiritual life and collective consciousness of the people, thus commemorating the contributions and virtues of the Mother Goddess to this land”.
