Song Dynasty is a very secular dynasty, because Song Yi was born in a family at the bottom of society, and he was in contact with people at the bottom of society. At that time, people at the bottom of society had the habit of calling the emperor a butler, so it was not easy for Zhao Kuangyin to change his tune immediately after he became emperor. Coupled with some complicated political reasons, Zhao Kuangyin always called himself a butler.

And the official mainly refers to a profession at that time. For example, a farmer or a family is called a farmer. From the perspective of Song Dynasty, an emperor or an official can be called an official.

The word housekeeper source:

The word "housekeeper" comes from Jiang Ji's On Wanji in Cao Wei period. In "On Wanji", he said: "Huang San is the official of the world, and the five emperors are the masters of the world", so the official in the Song Dynasty actually has a lot of connotations, and at the same time it takes into account the good names of the three emperors and five emperors, which is similar to the title of emperor invented by Qin Shihuang.

The so-called "Huang San is the official of the world and the five emperors are the masters of the world" is called "official" because the emperor should be selfless.

A wise emperor has no personal love and wealth. The emperor rules the world on behalf of heaven, and everyone in the world should treat the emperor equally.
