What does the double seal in the fate of the eight characters mean?

If the Japanese Lord is weak, self-protection is a good thing, and the seal is to protect you and to support you. Among the eight characters and five elements, the birthday star and five elements are printed stars. For example, the sun is the wood, aquatic wood, and water is the Indian star. Too many stars are bad for father, children and wife. More than three, forget it.
