What is auspicious?

In the past, when choosing a date, we should do something on an auspicious day to enhance the auspiciousness and smoothness of the action.

Auspicious God: When heaven, morality, man and heaven are in harmony, dogs should be tamed in addition to God.

Appropriate: sacrifice, break ground, undress, move clothes, and start digging wells to bury the soil?

In ancient times, people believed in the existence of gods, so in the days when there were many auspicious gods, smoothness and auspicious meaning could be increased.
