How many years is the life span of one year?

Ji is a calendar term in ancient China, which originated from the ancient times when ten days were combined with twelve earthly branches to form sixty jiazi, each jiazi was a year, and sixty years was a year.

Each cycle corresponds to the zodiac, so every 12 years is a cycle, and the "cycle" in the ancient population is 12 years.

One-year life refers to a specific period of the human world, about 10 thousand years.
