Princess Liễu Hạnh (Vietnamese: Liễu Hạnh Công chúa, chữ Hán: 柳杏公主)[1][2] 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.
[4] 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.
A righteous man, Lê Thái Công, was knocked unconscious during his wife (Trần Thị Phúc)'s pregnancy by a Taoist with his jade hammer.
When Giáng Tiên died she ascended to Heaven and was granted the title of Princess Liễu Hạnh, and was permitted to return to earth on the second anniversary of her death.
[citation needed]Long after her family died, she visited a temple and met Phùng Khắc Khoan, a famous scholar, who attempted to compliment the princess.
They married and had a son named Mai Thanh Cổn (later worshipped as Cậu bé Đồi Ngang in Đạo Mẫu), Sinh becoming a great scholar.
The government built the new temple in Phố Cát Mountain, and proclaimed her "Mã Hoàng Công Chúa" (Golden Princess to Whom Sacrifices Are Made as to the God of War).
