The difference between prolonging life and breaking death in geomantic omen theory.

"Yan nian" and "Desperate" are two of the eight stars in the geomantic omen of Bazhai. Their differences are as follows: first, prolonging life is a good star, while breaking death is a bad star. Second, the geomantic omen of Bazhai is based on the direction of the door or the direction of the house (Fu Gua), which gives birth to eight stars (including life-prolonging and death-prolonging) by the transformation of the divinatory symbols in order. The life-prolonging star is the birth and prosperity of the divinatory symbols transformed from this divinatory symbol, so it is auspicious. Desperate is the tomb and dead hexagram transformed from this divination, so it is fierce.
