Legend has it that in the ancient Huangdi era, a fire burned in the distant horizon. Whoever got this fire could be reborn from the fire and never die. Later, I heard that this fire was kept in Huangdi's family. In order to stop people from fighting for the sacred fire and killing each other, Huangdi extinguished the fire. No one has mentioned the incident since.
Only many years later, there were rumors in the world that this fire had not been extinguished at all, but remained in the Huangdi family. As for who passed it on and how it was passed on, no one knows.
