What does the Dafa disc symbol mean?

Firdaria is an astrological method, which first appeared in Persia and Arabia. Planets in the astrolabe are in charge of life fortune in a certain period, which can be divided into Universiade and Universiade. A Universiade includes seven Universiades in Jin Mu, including water, fire, earth, sun, moon and moon. Except for two or three years at the intersection of the north and the south, each Universiade is about 1- 1.3 years.

Fada is divided into 78 years according to the constellation and 75 years according to the planet. Usually we count 75 years and then go back to our birthplace. In 75, the Sino-French plate was dominated by seven planets and the intersection of north and south.
