南定省
Her personal cult was created by women in Nam Định Province, in the village of Van Cat. It is believed that the cult was created by rice farmers in need of land and water, and at its peak was extremely popular. The cult was mostly suppressed during the Communist Party of Vietnam's early reign, as worship was considered to be Taoist in nature, and was a tool of oppression. However, after Doi Moi (begun 1986) the cult has been regaining popularity steadily.
