"Road History. Zen Tongji" records: "Ge Tian is Quan Tian. The dome is the image of power, so Ge Tian is the name. It governs, governs itself without speaking, and moves on its own without changing. It is so swaying that it is impossible to name it. ... So Mount Tai was sealed, currency was established, and the number of meetings was established, so it was stagnant and connected and the world was peaceful. The Ge Tian family governed the world, trusting without words and acting without transformation, and opened a prosperous era of harmony in the civil, military, and Taoist systems."
