Shallow layer test:

China's traditional calendar is based on heavenly stems and earthly branches's arrangement, combination and circulation, which means circulation and reappearance. It is this "recurrence" that makes it meaningful to choose a date to avoid it. The fundamental basis for the ancients to formulate calendars and determine auspicious days is the sun, the moon and the stars. Among them, the stars are the most critical factor in determining the date, and the Gregorian calendar basically does not consider these, so there is no so-called taboo.
