How to interpret the fat day in the yellow calendar?

Explain the general statements one by one, which is a bit complicated:

Explanation: Fat day, contrary to thin day, is another name for "sunny day" and "cloudy day" in folk appellation. Because the sun is full of yen and the yin is like the moon, that is, it is said that it is sunny and round.

Proof: Zeng Guofan once said, "Just read Japanese classics and Japanese history", and combining rigidity with softness is a metaphor for Yin and Yang. There is also a popular saying that reading classics on sunny days and reading history on cloudy days ... among them, odd days are considered as yang and even days are considered as yin.

Commentary: Yang/Gang/Feiri all refer to Yang in Yi. Later, it evolved into geomantic omen and became a method to calculate yang dryness and yin dryness. (Some people in modern times will count it backwards, and yang dryness is yin pulp ...)

Difference: In different daily life, we need to calculate different yang dryness and yin dryness, that is, fat days and thin days. For example, six livestock fattening days mean that it is suitable for building livestock pens. Similarly ... killing pigs is bound to be fat one day ... (see the article "The Eight Characters of Fortune Tellers")

Conclusion: The day of getting fat is not a fixed day, but a good day calculated under different comprehensive conditions such as life/work/life (this is also one of the main reasons why witches in the old days were supported by villages and lived a carefree life). But as a scholar ... you just need to look at the days of even and odd numbers to decide whether you are fat or thin.
