What are the connections and differences between western constellations and China Zhouyi Eight Diagrams?

I can 100% tell you completely responsibly that western constellations are used to coax children, which means nothing at all. They are used to satisfy the fantasy psychology of young people. Zhouyi can accurately predict everything before and after you, but it can actually give feedback. Western constellations are games, and Zhouyi is a cosmic super science. There is no comparability between them. And I tell you, western constellations don't even believe in westerners themselves, but they become gods in the eyes of children in China. Quite absurd
