What is Tứ Bất Tử?
Tứ Bất Tử is the collective name for four immortal saints in Vietnamese folk belief: Tản Viên Sơn Thánh, Saint Giong, Chử Đồng Tử, and Holy Mother Lieu Hanh.
Also called: Four Immortals

What are the Tứ Bất Tử?
Tứ Bất Tử (the Four Immortals) is the collective name for four saints revered by the Vietnamese across many generations: Tản Viên Sơn Thánh, Thánh Gióng, Chử Đồng Tử and Thánh Mẫu Liễu Hạnh. The word "bất tử" (immortal) here does not mean living forever in the body; it refers to saints whose merits or cultural symbolism have been remembered and worshipped by the people over the long term. They became spiritual models for the community across many historical periods.
Origin and how the group took shape
These four saints are tied to different legends and mythical accounts, passed down among the people and gradually systematized within the Vietnamese tradition of saint worship. Tản Viên Sơn Thánh is tied to the legend of Sơn Tinh - Thủy Tinh, a symbol of the aspiration to master nature and to fight floods. Thánh Gióng is tied to the legend of fighting the Ân invaders, a symbol of the strength of resistance against foreign invasion. Chử Đồng Tử is tied to the myth of love and filial devotion. Thánh Mẫu Liễu Hạnh is tied to the myth of three descents to earth, and is the only female saint in the group.
Why are they called the four immortals?
The name "immortal" emphasizes how enduring these figures are in spiritual and cultural life. Each one represents a different aspect of life: fighting natural disasters, resisting foreign invasion, love and filial duty, and the role of women in Mother Goddess worship. Through festivals, temples and shrines, and folk stories, their images are recreated and passed on to later generations.
Distinguishing them from easily confused concepts
Tứ Bất Tử is not the single group of supreme deities in all of Vietnamese belief; it is a particular name for four representative saints. It should be distinguished from the "Tứ Pháp" (four deities associated with natural phenomena such as Cloud, Rain, Thunder and Lightning) and from the systems of deities in Buddhism or Taoism. Worship of these saints is traditional and for reference, and has not been verified by science.
Meaning in cultural life
Tứ Bất Tử reflects how the Vietnamese remember and honour community values through the images of saints and deities. Festivals such as the Gióng Festival in Hanoi have been inscribed by UNESCO as intangible cultural heritage, showing the vitality of these legends in contemporary life.
