What is taiyi noble?

"Three Fates Meeting" said: "Tianyi is the god in the sky, and it is juxtaposed with Taiyi outside the gate of Weizi Henghe River, serving the emperor, going downstream for the third time, and having a bullfight at home for the second time ... It is called Paradise B, and its god is the noblest. Wherever I go, I avoid murder. "
