The so-called fate, in numerology, actually has two meanings: one is fate, which refers to the nature endowed by nature; Second, luck refers to the bad changes in various stages of life. All my life, I am lucky in an instant. In the eight-character theory of life, the so-called luck refers to the Universiade, which is a period of ten years in life. The fate and luck of the eight characters constitute the grand cornerstone of the eight-character theory, and show the life curve as a function of time.
