Liễu Hạnh

Princess Liễu Hạnh (Vietnamese: Liễu Hạnh Công chúa, chữ Hán: 柳杏公主) is one of The Four Immortals in Vietnamese folk religion, and also a leading figure in the Four Palaces belief of the Đạo Mẫu, in which she governs the Earth realm and represents the Heaven realm on behalf of Mẫu Cửu Trùng Thiên.

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.
