What are the years of pure yin in eight characters?

One in every 16 people is pure yin or pure yang, and it can't be said that there are all those years, because there is a cloudy year every other year, and it is very common to dry the eight-character pure yin in the shade on the 10 every month. First of all, the even branches in heavenly stems and earthly branches belong to Yin, and the heavenly stems are B, D, G, Xin and Gui. Gezhi: ugly, ugly, ugly, ugly, ugly, ugly, ugly. Because heavenly stems and earthly branches is only a combination of Yin and Yin and Yang Yang, with 30 each.

First of all, only ugly years, old years, old years, no next year, one year and happy years are considered lunar years, and half of them have been removed.

Secondly, in the case that the year is the animal year, only ugly, ugly, innocent and innocent months are considered to be born in the lunar year, leaving a quarter.

Third, in a month, only ugly, stupid, unified and sad days can be called cloudy, with half removed and one-eighth left.

On the last day 12 hour, six cloudy days and six sunny days, it was cut in half again, leaving one sixteenth.

That's it. It's simple. It's actually quite simple. Heavenly stems and earthly branches is a calendar. Combine fortune, numerology, etc. It's superstition, just like the advertisements we use now. For example, the time for me to answer questions now is 15 at 4: 52 am in August, which is a calendar, but if it is combined with the horoscope, it is also superstition. Yin-yang and five elements are the result of ancient people's exploration of the world, and they are an attempt to explain the world with limited known knowledge, which cannot be completely denied, so they have been preserved.
