The beginning of the universe is the Dao (L68). The Dao was divided into thirty parts in which thirty Milky Ways were formed (L70). Each Milky Way forms an immense elliptic spheroid on which a hundred thousand skies were created. Each sky was developed into a stellar system, that is to say, there are a hundred thousand stellar systems in each Milky Way. Then celestial bodies were formed one after another. Fifty billion years passed between the creation of the stellar system and the celestial bodies (L62). The Eight Diagrams and Fishes of Yin and Yang here were used for creating the Milky Way and dividing the skies before the earth was formed.
