Why did the fortune teller say that my horoscope is twelve characters? Any explanation? Is it good or bad?

The eight characters are the date of birth. One day's work, one day's work, one day's work, one year's work and one month's work add up to eight words. Collectively called the eight characters, they are actually four pillars. The other four words are Universiade and fleeting time. One for the Universiade and the other for the fleeting time, adding up to twelve words. For example, this year is the year of Renchen, Renchen is the heavenly stem, and Chen Chen is the earthly branch.
