What does "the moon is dying" mean in the fortune-telling book?

Yuede refers to Noble Moon, one of the four gods. Those who saw it on the pillar were Noble Moon Tiande and Noble Moon. They met the sun and the moon. Life is easy to understand, it is arrival. You will understand after reading this passage ~

Yuede is the virtue of the lunar calendar, and its function is slightly similar to that of Tiande. The moon's virtue enters life, and the main blessing is far-reaching, longevity, and no official punishment. Tiande is Yang De, its function is obvious, Yuede is Yinde, and its function is hidden. When Tian Yue attends the meeting, the strength will be concentrated, which will benefit the world and society, and all the blessings will be gathered.
