From the perspective of sixty years, we must first know the person’s birthday and birth date, and then calculate it.
There are ten stems and twelve branches. The yang stem is matched with the yang branch, and the yin stem is matched with the yin branch. The remaining two branches are matched from the A, and the ten stems and the twelve branches are combined to obtain the least common multiple: 60, so it is called Sixty Years, also called Sixty Flower Years.
