How to understand the book Tang Fu by Sukarnoputri?

To understand the Gregorian calendar, we must first understand the twelve constellations.

Only then did I know what the twelve-day "construction, division, fullness, equality, determination, action, extinction, danger, success, integration, opening and integration" meant. The earth revolves around the sun for one year. According to the position change of the sun on the ecliptic and the evolution order of the ground climate, the ancients divided a year into 24 sunsets and 12 months. Therefore, based on the month, the twelve constellations are used to reflect the influence of cosmic celestial bodies on every day. The yellow underworld attributes of the 12 satellites are: building a flat and collecting black, eliminating danger will definitely be yellow; It can be used for opening and closing, but it is unlucky if it is broken. Black doesn't love, yellow is not strong.

The yellow calendars we want to see are basically good luck, avoiding evil, and choosing good luck. The simplest view is that the days when the scarlet letter is printed are basically auspicious days. Today, what is appropriate and what is taboo will be clearly written on the yellow calendar, and you can check it against the date.
