What is Tai Chi number?

Tai Chi, chaos, is a day. Taiji No.1 is derived from two instruments and two numbers, and the number of places is two.

Tai Chi is one plus two, and you get three days.

Taiji in the third grade repeatedly deduces the number of two instruments and adds the original number of two instruments to get the number of four.

Four plus Tai Chi is five days.

Tai Chi in Five Days and Five Middle Schools has repeatedly deduced that the number of two instruments plus the original four places is six.

If Tai Chi is one plus six, you have seven days.

On the seventh day of Taiji, the number of two instruments was deduced several times, and the original six digits were added to get eight digits.

If Tai Chi is one plus eight, the number of days is nine.

In nine days, Taiji repeatedly derived the number of two instruments plus the original eight places, resulting in dozens of places.

In the above figures, all even numbers (including even numbers in days) are derived from Taiji I, and the sum of the derived numbers is fifty. This is the origin of the great (great) face number fifty.
