How to determine the yin and yang of a fifty-cent coin

In principle, the divination copper coin used by Mr Yao Gua is Gan Long Bao Tong. Because there is online divination now, many divinations are replaced by other coins without copper coins. Which side is yin and which side is yang? It's actually quite simple. The side with numbers printed on it is yin, and the side without numbers is yang. All coins, the world is unified, with numbers printed on one side and no numbers printed on the other. Any coin that is really spent as money can't be wrong.

Customs are yin and yang (usually the word is yin and the flower is yang)

Throw it six times and draw a picture each time (from bottom to top). Three yin is old yin (yin changes to yang), three yang is Lao Yang (yang changes to yin), one yin and two yang are shaoyin, and one yang and two yin are shaoyang. The probability of each appearance of Yin and Yang is 1/2, and the probability of change of heart is 1/4.

After throwing it six times, you can draw the original hexagrams and change your mind.
