When looking at horoscopes, we generally say that fortune comes once every ten years. When looking at the Universiade, we look at the Heavenly Stems and Earthly Branches at the same time. However, there are also those who divide the ten years into the first five years to look at the Heavenly Stems and the next five years to look at the Earthly Branches, that is According to this theory, every year when the Heavenly Stem is Xin and the year when the Heavenly Stem is C is the year when your fortune will be handed over, that is to say, the 23rd day after the Beginning of Summer in the year Xin or C ( Around June 1st in the Gregorian calendar) your luck will change from the original luck to the new luck. The changes in fortune before and after the luck are more obvious, you can feel it for yourself.
